	FADE IN:

1    INT. TEN-FORWARD (OPTICAL)

	WORF is seated at a table near one of the windows. The
	ship is traveling at WARP SPEED and the stars STREAK
	by. GUINAN comes over to Worf's table and delivers
	a drink to him.

					GUINAN
			Try this.

					WORF
				(looks at drink with
				 suspicion)
			What is it?

					GUINAN
			Just try it.

	Worf takes a cautious sip, then reacts with pleasure.
	He looks at her with surprise.

					GUINAN
				(smiles)
			It's an Earth drink... prune
			juice.

	Worf takes another belt of this marvelous concoction
	and nods with pleasure.

					WORF
			A warrior's drink.

	Guinan sits down at the table.

					GUINAN
			You're always drinking alone.
			It wouldn't hurt you to look for
			a little...
				(glances at a YOUNG
				 COUPLE at nearby table)
			...companionship.

	Worf looks at her with vague irritation. This
	conversation is venturing into areas he'd rather avoid.

    STAR TREK: "Yesterday's... " - REV. 12/11/89 - TEASER    2.

1    CONTINUED:

					WORF
				(measured)
			I would require a Klingon woman
			for... companionship. Human
			females are too fragile.

					GUINAN
			Not all of them... I know one or
			two on board who might find you
			a bit tame...

					WORF
			Impossible.

					GUINAN
			You never know until you try...

					WORF
			Then I will never know.

					GUINAN
			Coward...

					WORF
			I am merely concerned for the
			safety of my crewmates.

	Guinan nods -- "oh, right."

					GUINAN
			Drink your prune juice.

	The view out the window abruptly changes as the ship
	DROPS OUT OF WARP. The stars cease to streak by, and
	far out in front of the ship, a RIFT can be seen in
	space. The rift resembles a large jagged tear in space
	within which can be seen a maelstrom of changing colors
	and patterns.

2    ON GUINAN AND WORF (OPTICAL)

	who both react to the view and the rift. Worf is
	already starting to rise when he hears...

					RIKER'S COM VOICE
			Lieutenant Worf, report to the
			bridge.

					WORF
				(heading out)
			On my way, sir.

    STAR TREK: "Yesterday's... " - REV. 12/11/89 - TEASER    3.

2    CONTINUED:

	Guinan steps toward the window with a look of concern
	on her face. She can sense something... confusion,
	dread, possibly a trace of fear cross her face. Linger
	on her expression then...

									CUT TO:

3    EXT. SPACE - ENTERPRISE AND RIFT (OPTICAL)

	The ship hangs before the gaping rift in space.

4    INT. MAIN BRIDGE (OPTICAL)

	PICARD, RIKER, TROI in Command, WESLEY at Con, DATA at
	Ops. Worf ENTERS and goes to Tactical.

					PICARD
			Analysis, Mister Data.

					DATA
			Sensors are reading gravimetric
			fluctuations... most unusual
			ones.

					RIKER
			"Unusual" how? Specify?

					DATA
			Nothing I have seen before.

					PICARD
			Is it a wormhole?

					DATA
			Yes... and no. Like a... time
			displacement, but it does not have
			a discernible event horizon.

					WESLEY
			Sir, navigational subsystems are
			unable to give coordinates on the
			object.

    STAR TREK: "Yesterday's... " - REV. 12/11/89 - TEASER    4.

4    CONTINUED:

					DATA
				(checks console)
			Confirmed. The phenomenon does
			not have a definable center or
			outer edge.

					RIKER
			Are you saying it is... and yet
			it isn't there?

					DATA
			I do not have sufficient
			information to make an analysis
			as yet, Commander. The dynamics
			of the radiation patterns---

5    ON WORF

	He sees something on his tactical display and
	interrupts Data.

					WORF
			Something's happening, Captain.
			A new change in sensor readings.

6    INT. TEN-FORWARD

	Guinan is still looking out the window. Her puzzlement
	turns to alarm.

					GUINAN
				(almost a whisper)
			No...

7    EXT. SPACE - THE RIFT (OPTICAL)

	The colors within the rift change, swirl, shift... a
	SHIP suddenly appears. It is barely visible and no
	identification of design or type is possible yet.

8    INT. MAIN BRIDGE - CLOSE ON PICARD

	His eyes fixed on the viewscreen... his voice
	strangely echoing...

					PICARD
			Mister Data?

    STAR TREK: "Yesterday's... " - REV. 12/11/89 - TEASER    5.

8    CONTINUED:

	PULL BACK to reveal the rest of the bridge except for
	the Tactical station. (NOTE: history has just been
	changed although none of our characters realize it)
	The bridge has now been ALTERED to suggest a more
	militaristic atmosphere. The mood is darker, more
	somber... our comfortable bridge is more like the nerve
	center of a battleship than of an explorer. Even our
	uniforms have been slightly altered to emphasize rank
	and status.

	Troi is gone. Wesley now wears a regular Ensign's
	uniform... what were once science stations are now
	damage control centers... SECURITY SUPERNUMERARIES
	with sidearms are posted near all turbolifts...
	Picard's chair is larger and more impressive... patches
	and scars on the bulkheads attest to the action the
	ship has seen recently. The attitudes of our
	characters are more military and formal. These people
	have been hardened slightly and are not the relaxed,
	at ease people we've come to know.

					PICARD
			Can you identify the ship,
			Lieutenant? Is it an enemy
			vessel?

	MOVE TO TACTICAL and now reveal TASHA at station. The
	Tactical station itself has been expanded and enhanced
	with more panels and displays. Tasha replies crisply
	and efficiently... as if she had never been anywhere
	else.

					TASHA
				(shakes head)
			I'm getting too much interference,
			Captain.

8A   EXT. SPACE - THE RIFT (OPTICAL)

	The ship within the rift is more clearly visible. It
	is unmistakably a starship of an earlier design than
	our own. It is very battered and beaten and looks as
	though it's been to hell and back.

8B   INT. MAIN BRIDGE

	As before.

					TASHA
			It's clearing, Captain.
			Definitely a Federation
			starship... accessing registry...

       STAR TREK: "Yesterday's... " - 12/8/89 - TEASER       6.

8C   ON MAIN VIEWER (OPTICAL)

	The other ship, hereafter called Enterprise-C, can be
	seen and the heavy damage is apparent.

					RIKER (O.S.)
			Looks like they had a rough ride.

8D   NEW ANGLE

					TASHA
				(reading display with
				 surprise)
			N, C, C, one-seven-oh-one... C.
			U.S.S.... Enterprise.

	On reactions...

									FADE OUT.

	FADE IN:

9    EXT. SPACE - THE TWO ENTERPRISES (OPTICAL)

	Enterprise-C in f.g. with name and designation number
	clearly visible. Enterprise-D in b.g.

					PICARD (V.O.)
			Military log, Combat-date
			43625.2. While investigating an
			unusual radiation anomaly reported
			by Starbase one oh five, the
			Enterprise has encountered what
			could almost be called a ghost
			from its own past... The
			Enterprise-C, the immediate
			predecessor of this battleship.

10   INT. MAIN BRIDGE

	As before.

					DATA
			Sensors confirm design and
			specifications, Captain. Analysis
			of hull and engine materials
			conform to engineering patterns
			and methods of that time period.

					WESLEY
			But that cruiser was destroyed
			with all hands about twenty years
			ago.

					DATA
			Presumed destroyed. The
			Enterprise-C was last seen near
			the Klingon outpost on Narendra
			Three exactly twenty-two years,
			four months and three days ago.

					RIKER
			And now it's here.

					PICARD
			Mister Data, is it possible...
			that it has... traveled through
			time?

   STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT ONE   8.

10   CONTINUED:

	Everyone's been thinking the same thing, but hearing it
	actually said out loud makes them all take another look
	at the ship sitting in front of them.

					DATA
			It is a possibility, Captain.
			If that is the correct hypothesis,
			then the phenomenon we just
			enountered was a temporal rift
			in space.

					PICARD
			A rift?

					DATA
			Possibly the formation of a Kerr
			loop from superstring material...
			it would require high-energy
			interactions occuring in the
			vicinity for such a structure to
			form. The rift is certainly not
			stable, Captain. It could
			collapse at any time.

					TASHA
				(eyes on tactical
				 display)
			I'm able to scan the interior of
			the ship now, sir... heavy damage
			to warp field nacelles and hull
			bearing struts... internal space
			frame --
				(shock at new reading)
			Life-signs, Captain!

	Picard and Riker react.

					TASHA
			Readings are sporadic... looks
			like they have massive casualties,
			but some are still alive.

					RIKER
				(to com)
			Bridge to Sickbay. Emergency
			teams, stand by Transporter Rooms.

					BEVERLY'S COM VOICE
			Understood.

	Picard gives Riker a look:

   STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT ONE   9.

10   CONTINUED: (2)

					PICARD
			Belay that order, Doctor.

					RIKER
			I respectfully suggest that
			regardless of how they did it,
			they are here now and they need
			our help.

					PICARD
			That ship has traveled into its
			own future. We are dealing with
			variables that could alter the
			flow of our own history.

					RIKER
			But their influence on history
			has ended, sir. That ship
			disappeared from the past
			twenty-two years ago and never
			returned.

	Before Picard can reply, Tasha interrupts them.

					TASHA
			Captain, the Enterprise... C is
			sending out a distress call, sir.
			Audio only.

	Picard nods.

					GARRETT'S COM VOICE
				(strained as if in pain)
			This... is Captain Garrett... of
			the Starship Enterprise, to any
			Federation ship. We... have been
			attacked by Romulan warships and
			require... immediate assistance.
			We have lost warp drive...
			life-support is failing.

					RIKER
			We have no record of a Romulan
			assault on the Enterprise-C...

					TASHA
			Voice message has ended, Captain.
			All I'm receiving now is their
			automated distress signal.

	All eyes turn to Picard. He looks at the Main Viewer
	as he makes his decision... a long tense moment.

   STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT ONE   10.

10   CONTINUED: (3)

					PICARD
			Hailing frequency, Lieutenant.
			This is Captain Picard of... a
			Federation starship. Standby to
			receive emergency teams.

	The only response is STATIC.

					PICARD
				(to Riker)
			We'll handle this one step at a
			time. Stabilize power systems
			and attend to their casualties.
			Avoid discussions of where and
			when they are.

					RIKER
			Aye, sir.
				(heads to turbolift)
			Lieutenant.

	SUPERNUMERARY goes to Tactical. Tasha and Riker EXIT.

					WESLEY
				(reading console)
			Message coming in from Starfleet
			monitor stations, Captain.
			Klingon battlecruisers have been
			reported moving toward this
			sector.

	This is not welcome news.

					PICARD
				(grimly)
			Battle alert, Mister Crusher.
			Condition Yellow.

	bridge alert status goes to YELLOW and we hear a new
	ALERT SOUND.

					WESLEY
			Aye, sir.
				(works console)
			All decks report Condition Yellow.

12A  INT. TEN-FORWARD

	Which is somewhat different than we last saw it... no
	civilians... about twenty UNIFORMED CREWMEN and WAITERS
	all carrying sidearms. Not as casual... more a
	military canteen/mess hall than a lounge.

	Guinan's expression is puzzled. She's walking around.
	She frowns and shakes her head.

					GUINAN
				(to no one in
				 particular)
			It's changed... it's all
			changed...

	A customer overhears, gives her an odd look... she
	moves quickly to EXIT.

13   EXT. SPACE - ENTERPRISE-C (OPTICAL)

	The battered starship drifts in space.

14   INT. ENTERPRISE-C BRIDGE (OPTICAL)

	The bridge has been heavily damaged. RED ALERT is in
	effect. FOUR SUPERNUMERARIES are lying dead on the
	deck plates or at their consoles. Smoke lingers in
	the air and burning panels add their own eerie
	lighting. Slumped in the captain's chair is RACHEL
	GARRETT, a tall, handsome woman that commands respect
	instantly. She is injured and barely holding on to
	consciousness. Riker, GEORDI, BEVERLY, and Tasha BEAM
	onto the bridge. Beverly moves to a crewman lying on
	the deck, Geordi goes to what's left of the engineering
	console, and Riker and Tasha go to Garrett.

					RIKER
			Captain Garrett?

					GARRETT
				(through fog of pain)
			Yes.

					RIKER
			I'm Commander Riker. We have
			emergency teams boarding your
			ship.

			Doctor.

	Beverly goes to Garrett and runs a tricorder over her.

					BEVERLY
				(quietly to Riker)
			The rest of the bridge crew is
			dead.
				(reading tricorder)
			Her leg is fractured and she has
			serious internal injuries.
					(MORE)

      STAR TREK: "Yesterday's... " - 12/8/89 - ACT ONE      12.

14   CONTINUED:

					BEVERLY (Cont'd)
			I'll have to get her back to the
			Enterprise, it's more than I can
			do here.

					GARRETT
				(fighting to make sense
				 of it all)
			To where?

					RIKER
			We'll explain later, Captain.

					GARRETT
				(summons some steel)
			You'll explain now, Commander.

					RIKER
			We're from a Federation starship.
			We've answered your distress call.
			Your ship is in good hands, but
			we need to get you to our Sickbay.

					GARRETT
				(reluctantly)
			Very well.

					BEVERLY
				(activates com badge)
			Crusher to Transporter Room. Two
			to beam directly to Sickbay.

	Riker stands back as Beverly and Garrett BEAM out. He
	goes over to Geordi.

					GEORDI
				(shaking his head at
				 console)
			Pretty bad, Commander. Looks like
			they were in a hell of a fight.

					RIKER
			If you can't stabilize
			life-support, we'll have to
			evacuate the ship.

					GEORDI
			I think we can do it. I'll have
			to get to Engineering...

	Riker gives him a curt nod and Geordi moves toward
	emergency exit.

   STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT ONE   13.

14   CONTINUED: (3)

				(activates com badge)
			La Forge to damage control team
			alpha. Meet me on Engineering
			level three.

	Geordi EXITS. A RASPING OF METAL is heard coming from
	one of the collapsed bulkheads. Tasha moves quickly to
	the wall and manages to move some of the material with
	Riker's help.

15   NEW ANGLE

	on Tasha and RICHARD CASTILLO, who is lying under the
	rubble. Castillo is ruggedly handsome, with jet black
	hair and fiery eyes. He is apparently just regaining
	consciousness, but otherwise does not look injured.

					CASTILLO
			Thanks...

	Castillo gets up, he's still a bit wobbly on his feet.
	He looks at Tasha and Riker and tries to put his
	memories in order. Riker wants to head off this
	discussion for now.

					RIKER
			I'm Commander Riker.

					CASTILLO
			Lieutenant Castillo. Helmsman.

					RIKER
			Your Captain has been sent back
			to the Ent--... back to our ship.
				(glance around bridge)
			You would appear to be the senior
			officer left aboard.

	Castillo looks around the shattered bridge. The
	destruction, though no surprise to him, is still
	shocking. His gaze travels over the bodies of his
	former shipmates.

					CASTILLO
				(quietly)
			So it would appear.

	As Tasha and Riker exchange a look...

19   ON VIEWSCREEN (OPTICAL)

	Riker appears on the viewscreen. He is standing on the
	bridge of the Enterprise-C.

					PICARD (O.S.)
			Go ahead, Commander

					RIKER
			We've stabilized life support,

					PICARD
			Survivors?

					RIKER
			One hundred twenty-five, sir

					WESLEY
				(softly)
			Out of seven hundred.

					PICARD
			Recommendation?

					RIKER
			I'd hate to scrap her, sir.
			Starfleet could certainly use
			another ship, even if it is a
			little old.

      STAR TREK: "Yesterday's... " - 12/8/89 - ACT ONE      15.

20   CONTINUED:

					PICARD
			Agreed. But we can't stay in this
			area too long.
				(makes decision)
			You have nine hours. If you can
			get her underway in that time,
			we'll escort her back to Starbase

			evacuate the survivors and destroy
			the ship.

					RIKER
			Understood, sir.

21   ON TURBOLIFT

	Guinan ENTERS. She looks around the bridge. It looks
	familiar, yet somehow wrong to her... just like
	everything else aboard.

21A  NEW ANGLE

					PICARD
			Keep me posted, Picard out.

	Picard turns away from the viewscreen and sees Guinan
	for the first time. Her appearance on the bridge is
	somewhat unprecedented and Picard is very surprised.

					PICARD
			Guinan... ?

23A  EXT. SPACE - THE TWO ENTERPRISES (OPTICAL)

	As before.

24   INT. READY ROOM

	Guinan and Picard talking.

					GUINAN
			I don't know...

					PICARD
			You must have some idea how things
			have changed...

					GUINAN
			I look at things... at people...
			and they don't feel right.

					PICARD
			What things? What people?

	Guinan looks around helplessly for an example, settles
	on Picard himself:

					GUINAN
			The bridge...

					PICARD
			What's the matter with it?

					GUINAN
			It's not right.

					PICARD
			It's the same bridge, Guinan. It
			hasn't changed.

	Worried, confused -- she sits. Knowing but being
	unable to explain... her placid nature cannot mask her
	frustration... it's more frightening than anything
	she's ever known.

					GUINAN
			I know that. And I also know...
			it's wrong.

  STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT TWO  16A.

24   CONTINUED:

	Her eyes look to Picard almost apologizing, needing to
	be believed... Picard takes a deep breath, sits.

					PICARD
			What else?

	Feelings... reaching inside for feelings... almost to
	herself --

   STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT TWO   17.

24   CONTINUED: (2)

					GUINAN
			Families. There should be
			children here...

					PICARD
			Children? On the Enterprise... ?
				(she nods)
			We're at war, Guinan.

					GUINAN
				(quick)
			No, we're not.
				(beat, thoughtful)
			I mean, we shouldn't be. This
			is a ship of peace. Not of war.

					PICARD
				(beat)
			Guinan, what you're suggesting...

					GUINAN
			It's not a suggestion, Captain.
			And that ship from the past...
			it was not supposed to come here.
			It's got to go back.

	On his reaction...

24A  INT. ENTERPRISE-D SICKBAY (FORMERLY SCENE 17)

	Garrett is lying on a table while Beverly and a MEDICAL
	SUPERNUMERARY work on her. In b.g., TWO MORE
	SUPERNUMERARIES tend to FOUR INJURED ENTERPRISE-C
	CREWMEMBERS. Garrett is awakening, looks around the
	Sickbay. She's beginning to realize that this isn't
	just another starship. She looks at the instruments
	that Beverly is using with curiosity... they don't seem
	quite familiar to her. She looks over as Picard
	ENTERS.

					PICARD
				(to Garrett)
			I'm Captain Picard.

					GARRETT
				(tries to sit up)
			Rachel Garrett. How's my ship?

					PICARD
			Life support systems have been
			restored. Repairs are continuing.

      STAR TREK: "Yesterday's... " - 12/8/89 - ACT TWO      18.

24A  CONTINUED:

	She leans back, relaxes...

					GARRETT
			Where did you come from? We
			weren't picking up any other
			Federation ships in this sector...

	Picard and Beverly exchange a glance...

					PICARD
				(avoiding her question)
			What is the last thing you
			remember?

					GARRETT
			We were answering the distress
			signal...

					PICARD
			Distress signal... ?

					GARRETT
			You must have heard it. From the
			Klingon outpost, Narendra Three.
				(off his look)
			But you didn't... did you?

	Garrett looks around the Sickbay again.

					GARRETT
			I've never seen a Sickbay like
			this... not even on a starbase.
			And your uniforms...
				(firmly)
			What ship is this, Captain?

					BEVERLY
			Please... try to keep still...

	Picard struggles with the decision for a moment.

					GARRETT
			I insist on an answer.

					PICARD
			You are aboard the Enterprise,
			Captain... one-seven-oh-one-D.

	He lets that sink in for a second. Garrett grasps the
	implication after a moment and her expression is
	shocked. Picard nods...

      STAR TREK: "Yesterday's... " - 12/8/89 - ACT TWO      19.

24A  CONTINUED: (2)

					PICARD
			You have come twenty-two years
			into the future.

					GARRETT
			Twenty-two years.

	It's a difficult realization for even a starship
	captain.

					GARRETT
			Does my crew know yet?

					PICARD
			No.

					GARRETT
			I must tell them... I owe them
			that, Picard...

					PICARD
				(reluctantly)
			If you wish, I will see to it that
			they're informed...

	Garrett is puzzled by Picard's reticence.

					GARRETT
			Is there a reason they should not
			be told?

					PICARD
			I am concerned that if you return
			to your own time with knowledge
			of the future...

					GARRETT
			Return? To the battle? We barely
			escaped with our lives. If we
			return, we'll be destroyed.

	A beat. Picard nods, this is not the time to discuss
	Guinan's feelings.

					PICARD
			Have you any idea how this
			happened?

   STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT TWO   20.

24A  CONTINUED: (3)

					GARRETT
				(shakes her head)
			There was a fierce volley of
			photon torpedoes... we were hit...
			there was a bright light and
			then... here.

					PICARD
			It is possible your exchange of
			fire was the catalyst for the
			formation of a temporal rift.
				(beat)
			History never recorded your battle
			with the Romulans.

					GARRETT
				(weary)
			We were responding to a distress
			call from the Klingon outpost on
			Narendra Three... the Romulans were
			attacking it... we engaged them...
			but there were four warbirds.

					PICARD
			The Narendra Three outpost was
			wiped out.

	Remembering what Guinan said --

					PICARD
			It is regrettable you did not
			succeed, Captain. If a Federation
			starship had rescued a Klingon
			outpost... it might have averted
			twenty years of war.

	Off her reaction...

	Tasha is more tuned to her panels and monitors... not

					TASHA
			What are the status readouts on

					CASTILLO
			Emitters available -- sixty
			percent forward, fifty-two percent
			aft.

					TASHA
				(acknowledges)
			Let's take a look at the torpedo
			launchers...

					CASTILLO
				(still lost in thought)
			I guess I'm lucky to be alive at

					TASHA
			You may not like the future. It's
			been a long war. The
			Federation's lost more than half
			of Starfleet to the Klingons.

					CASTILLO
				(reacts)
			We were negotiating a peace treaty

			A lot of changes, Lieutenant.
			A lot of changes.

	He nods. A beat.

30B  INT. MAIN BRIDGE - ENTERPRISE-D

	At an aft science station... Picard looks over Data's
	shoulder as he studies a computer graphic on a
	monitor...

					DATA
			The probability is high that the
			temporal rift is symmetrical,
			Captain.

					PICARD
			If that is the case, what would
			happen if the Enterprise-C were
			to fly back through it?

					DATA
				(reacts)
			Back, sir? The Enterprise-C would
			emerge in her own time period
			at almost the same instant she
			left.

					PICARD
			Right in the middle of her
			battle with the Romulans.

					DATA
			Yes, sir.

					PICARD
			Based on the logs of the

			None, sir.

	Castillo nods to Garrett. It's their first meeting

					GARRETT
			Lieutenant, how's the ship?

					CASTILLO
			We've restored minimal shields
			and the forward phaser banks.
			Still no photon launchers or warp
			drive.

					GARRETT
			Concentrate on the weapon systems.
			From what Captain Picard has told
			me, the Federation can use all
			the help it can get.

					TASHA
			And soon. Our sensors have picked

	Garrett reacts...

					GARRETT
			Why wasn't I informed, Mister
			Castillo... ?

	She begins to rise...

					CASTILLO
			Captain, you shouldn't --

					GARRETT
				(cutting him off)
			As senior officer, I want you to
			be my liaison to the Enterprise-
			D... coordinate with
			Tactical...

					TASHA
			That's me, Captain.

	Beverly rushes up, forces the Captain back on the bed.

					BEVERLY
			Where do you think you're going?

			I'm ready to resume my duties.

					GARRETT
			Nonsense. Doctors always

					BEVERLY
				(equally stubborn)
			And captains always push
			themselves too hard.

	Garrett stubbornly gets back on her feet.

					GARRETT
			Doctor, my ship and crew need me
			-- now. Twenty-four hours might
			as well be twenty-four years.

	And she EXITS to Crusher's chagrin.

35   INT. OBSERVATION LOUNGE

	Which has been converted into a war room atmosphere.
	The door slides open and Guinan ENTERS, pauses at the
	door, looking at --

36   NEW ANGLE - PICARD

	alone at the far end of the table filled with wartime
	displays and charts... they look at each other a beat.
	Picard is quite tense, a man who needs answers to make
	a difficult judgment.

					PICARD
			I need more.

	Guinan looks at him. She can't help him.

					GUINAN
			There is no more. I wish there
			was, Captain. I wish I could
			prove it. I can't.

 STAR TREK: "Yesterday's... " - REV. 12/13/89 - ACT THREE 27A.

36   CONTINUED:

					PICARD
			Then I can't send them back.

					GUINAN
			You must.

					PICARD
			Dammit, Guinan, they will die
			moments after they return... how
			can I ask them to sacrifice their
			lives based solely on your...
			intuition?

					GUINAN
			I don't know.

	And it is torture for her... not to be able to give him
	more... with uncharacteristic emotion --

					GUINAN
			This is a mistake. Every cell in
			my body knows this is a mistake.
			I cannot explain it to myself so
			I cannot explain it to you. I...
			just know.

  STAR TREK: "Yesterday's... " - REV. 12/13/89 - ACT THREE  28.

36   CONTINUED: (2)

					PICARD
			Who is to say this history is any
			less proper than the other?

					GUINAN
			I guess I am.

					PICARD
			Not good enough.
				(softly agonizing)
			Not good enough. I will not ask
			them to die.

					GUINAN
				(beat, softly)
			Forty billion have died in the
			war...

					PICARD
			I cannot justify readjusting
			history on the basis of saving
			lives in war... shall I return
			to Sarajevo and stop the
			assassination of Archduke
			Ferdinand... or go back to warn
			Station-Salem Four of the Bel-zon
			raid...

					GUINAN
			This war was never meant to be.
			They must return to their own
			time to correct that.

					PICARD
			And what is the guarantee that
			by going back they will
			succeed... ?

	She gives him a look -- there is none.

					PICARD
			In fact, they could conceivably
			create a third time line.

					GUINAN
			Yes.

					PICARD
			Every instinct tells me it's wrong
			and dangerous and futile.

  STAR TREK: "Yesterday's... " - REV. 12/13/89 - ACT THREE  29.

36   CONTINUED: (3)

	She moves closer to him... and if there is a sense of
	quiet power from Guinan that seems almost evangelical,
	it is intended.

					GUINAN
			Picard, we have been together for
			twenty-two years. I have been
			your advisor, your confidant, your
			friend and in all those twenty-two
			years, I have never led you
			astray. This time line cannot
			be allowed to continue. I've told
			you what you must do. You have
			only your faith in me to help you
			decide.

	On his reaction...

37   INT. TEN-FORWARD - WITH TASHA AND CASTILLO

	at the bar...

					TASHA
			Deflector shield technology has
			advanced considerably during the

	Move to find Guinan returning... moving behind the

			Have you ordered yet, Tasha?

			Not yet... Is something wrong,

					GUINAN
			Not a thing. What can I get you?

	Slightest beat. Tasha knows something's wrong.

			Hey, I've known you a whole day

				(smiles)
			Okay, Castillo.

				(beat, a little shy)
			Naw, I think maybe I'd like it

	And there's a charming boyish look in his eye that

	At corridor. Tasha pauses in the doorway.

					TASHA
			Data, how different do you think
			your life would be in the other
			time line?

					DATA
				(considers a beat)
			The possibilities are too numerous
			even for me to calculate, Tasha.

					TASHA
				(thinking to herself)
			Kind of scary, isn't it?

					DATA
			Scary? I would not know.

	She EXITS, the door closes and on Data's reaction...

50   EXT. SPACE - THE TWO ENTERPRISES (OPTICAL)

51   EXT. ENTERPRISE-C BRIDGE

	Tasha and Castillo work at the aft stations, doing
	additional checks...

					CASTILLO
			Shields are up to seventy-two
			percent... That's better...

	Moving to find Garrett and Picard, alone. He has just
	informed Captain Garrett of his feelings. She is
	thoughtful, not hostile, looking for solutions as is
	everyone else...

					GARRETT
			You believe this woman...

  STAR TREK: "Yesterday's... " - REV. 12/14/89 - ACT THREE  37.

51   CONTINUED:

					PICARD
				(nods)
			I discovered long ago that she
			has a special wisdom... I've
			learned to trust it.
				(beat)
			If you wish, I can arrange for
			you to speak with her...

					GARRETT
			Captain, I'd be lying to you if
			I told you there was a chance in
			hell of coming out of this alive.
			And my crew means a lot to me.

	Picard solemnly acknowledges, he knows.

					GARRETT
			Why doesn't your ship come back
			with us? The Romulans would be
			no match for your weaponry...

					PICARD
			I can't do that.

					GARRETT
				(beat, agrees on closer
				 examination)
			No, I suppose not. You don't
			belong in our time... any more
			than we belong in yours.
				(beat)
			To be honest, Picard, there are
			some members of my crew who have
			expressed a desire to return...
			even knowing the odds. Some
			because they can't bear to live
			without their loved ones... some
			who don't like the idea that we
			slipped out in the middle of a
			fight. But I've told them... that
			in the here and now, the
			Federation needs another ship
			against the Klingons... and we
			better get used to being in the
			here and now...

 STAR TREK: "Yesterday's... " - REV. 12/13/89 - ACT THREE 37A.

51   CONTINUED: (2)

					PICARD
			By going back, you may be a great
			deal more helpful. The war is
			going badly for the Federation.
			Much worse than is generally known.

	Forcing himself to say it.

					PICARD
			Starfleet Command believes defeat
			is inevitable... that within six
			months we will have no choice but
			to surrender...

	This hits home to Garrett. For a moment, she's too
	stunned to speak.

					GARRETT
				(softly)
			And you're saying all this may
			be a result of our arrival here.

					PICARD
			One more ship will make no
			difference in the here and now,
			Captain. But twenty-two years
			ago, one ship could have stopped
			this war before it ever started.

  STAR TREK: "Yesterday's... " - REV. 12/13/89 - ACT THREE  38.

51   CONTINUED: (3)

	A long beat. She glances at Castillo, nods.

					GARRETT
			Mister Castillo, inform the crew
			that we're going back.

					CASTILLO
			Yes, Captain.

	He exchanges a glance with Tasha, moves to an aft
	station.

					GARRETT
			The Romulans'll get a good fight.
			We'll make it one for the history
			books.

					PICARD
			I know you will, Captain.

	Picard nods with admiration for his counterpart. And
	as he takes his leave...

					PICARD
			Lieutenant Yar...

					TASHA
			Permission to remain for a moment,
			sir...

	Picard sees that she wants to say good-bye to
	Castillo...

					PICARD
			Granted.

	They EXIT to go the Transporter Room... Tasha goes to
	the aft station... Now that she's there, she doesn't
	know exactly what to say to him. Other
	supernumeraries are near-by -- what they might have
	said is forced into the most formal language.

					TASHA
			I just wanted to say good luck...

  STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT THREE  39.

51   CONTINUED: (3)

					CASTILLO
			I'll try to put some of your
			tactical briefing to good use when
			we get back...

					TASHA
			Your ship has a lot more
			maneuverability than the Romulan
			counterparts of that era... in
			fact, if you could isolate...

	She stops in mid-sentence, knowing she doesn't want
	to be talking techno right now...

					TASHA
			You'll do fine.

					CASTILLO
			If you get back to Earth... and
			you see a man, oh, in his late
			fifties taking a hard look at you
			across a crowded room...
				(she smiles)
			Hey, you never know.

	And she nods, forcing back her emotions... she puts out
	her hand...

					TASHA
			Good-bye, Lieutenant.

	As Castillo reaches for it... suddenly an EXPLOSION
	rocks the ship, throwing them off balance.

52   NEW ANGLE (OPTICAL)

	A Klingon bird of prey has appeared on the Main
	Viewer.

	Castillo rushes over to the helm... Tasha to tactical.
	Over this:

					GARRETT
			Red Alert. Full power to shields.

	Red Alert sounds.

					TASHA
			Shields are up. Functioning.

61B  INT. OBSERVATION LOUNGE

	Picard, Riker, Castillo, Tasha.

					CASTILLO
			I'm prepared to lead the
			Enterprise back myself, Captain
			Picard.

					RIKER
				(to Picard)
			Sir, Lieutenant Castillo is the
			last senior officer alive... he
			will have limited support from
			Ops, no Tactical, reduced staff
			in Engineering...

					CASTILLO
			I have good people willing to do
			their best...

					RIKER
				(to Castillo)
			But certainly, history never meant
			this ship to be led into battle
			without your captain.

					CASTILLO
			I can't speak to that point,
			sir... but I can get us back to
			where we're supposed to be. I
			believe that's what Captain
			Garrett would want me to do.

					DATA'S COM VOICE
			Commander Data to Captain Picard.

					PICARD
			Go ahead.

          STAR TREK: "Yesterday's... " - 12/8/89 - ACT FOUR          43.

61B  CONTINUED:

					DATA'S COM VOICE
			Sir, sensors are showing
			additional instability in the
			time rift. Possibly the result
			of the battle with the Klingons.

					PICARD
			Any signs of other Klingon
			vessels?

					DATA'S COM VOICE
			No, sir.

					TASHA
			I'm sure our coordinates have
			been transmitted to the Klingon
			command... we must not remain
			here.

	Picard studies the helmsman...

					CASTILLO
			Sir, it is my intention to return,
			unless you order me not to.

	Picard's eyes glow with admiration for the young
	lieutenant... Tasha watches with renewed concern, but
	she too respects him enormously.

					PICARD
			How soon will your ship be ready?

					CASTILLO
			We sustained moderate damage in
			the attack... I think we can get
			underway in a few hours...

					PICARD
				(to Riker)
			We will maintain position to
			provide cover.
				(to Castillo)
			Make it so.

	Castillo salutes the captain, Picard gives him a good
	tough salute in return... and he EXITS, followed by
	Tasha.

61C  INT. TRANSPORTER ROOM (OPTICAL)

	Tasha and Castillo ENTER. A supernumerary mans the

					CASTILLO
			One to beam to the Enterprise-C.

	The engineer acknowledges... he turns to Tasha.

					CASTILLO
			We keep saying good-bye... don't
			we?

					TASHA
			I wish there was more time.

					CASTILLO
			More time... I think we have all
			the time we can handle as it is.

	They look at each other and damn the engineer, they
	move together into a warm and tender kiss. When they
	break...

					CASTILLO
				(good-bye... )
			Lieutenant.

	And she watches as he moves to the transporter pad...
	and they look at each other with a love that might
	have been... and he DEMATERIALIZES... and as we push
	into her face, her thoughts racing...

	alone... looking at her...

					GUINAN
			What would you like?

					TASHA
			Guinan, I have to know something.

	Guinan looks at her evenly.

61E  CONTINUED:

					TASHA
			What happens to me in the other
			time line?

	A long beat.

					GUINAN
			I don't have alternate biographies
			of the crew, Tasha. I told the
			captain... it's just a feeling...

					TASHA
			But there's something more when
			you look at me, isn't there...

	A long beat.

					TASHA
			I've seen it in your eyes, Guinan.
			We've known each other too long...

					GUINAN
				(beat)
			We weren't meant to know each
			other at all.
				(off Tasha's look)
			Or that's what I sense when I look
			at you.

	Tasha looks at her with a curious smile...

					GUINAN
			You're not supposed to be here,
			Tasha.

					TASHA
			Where am I supposed to be?

					GUINAN
			Dead.

	Tasha is shaken as any of us would be... she tries to
	cover it. A beat.

					TASHA
			Do you know how?

					GUINAN
			No.
				(beat)
			But I know that it was an empty
			death. A death without purpose.

       STAR TREK: "Yesterday's... " - REV. 12/11/89 - ACT FOUR       46.

61E  CONTINUED: (2)

	As Tasha considers this revelation, her mind begins to
	work.

62   INT. READY ROOM

	Picard at his desk, working... a chime.

					PICARD
			Come.

	The door slides open and Tasha ENTERS.

					PICARD
			Yes, Lieutenant.

					TASHA
			Captain, I request a transfer to
			the Enterprise-C.

	Picard is taken by surprise.

					PICARD
			For what reason?

					TASHA
			They need someone at Tactical.

					PICARD
			You're needed here.

					TASHA
			Sir, I don't belong here.

					PICARD
				(reacts)
			Sit down.
				(she does)
			What did she tell you?

					TASHA
			I'm not supposed to be here. I'm
			not supposed to be alive.

	Picard is shaken by the revelation...

					PICARD
				(rather aghast)
			She felt it was necessary to
			disclose this to you?

					TASHA
			I felt it was necessary.

          STAR TREK: "Yesterday's... " - 12/10/89 - ACT FOUR         47.

62   CONTINUED:

					PICARD
			I see.
				(beat)
			You realize that it is very
			possible that the Enterprise-C
			could fail. We may be forced to
			remain in this time line... in
			which case your life would go on,
			hopefully for a long while.

					TASHA
			I know how important it is that
			they don't fail, Captain. That's
			why I'm requesting this transfer.

					PICARD
			Lieutenant, you don't belong on
			that ship...

					TASHA
			No. Captain Garrett belongs on
			that ship. But now that
			she's dead, there's a certain
			logic in this request.

					PICARD
			There's no logic in it at all.
				(beat)
			Tasha, whether they succeed or
			not, the Enterprise-C will be
			destroyed...

					TASHA
			At least, with a tactical officer
			on board, they will have a chance
			to defend themselves well,
			Captain... it may be a matter of
			seconds or minutes... but those
			could be the minutes that change
			history...
				(beat)
			Guinan says I died a senseless
			death in the other time line.
			I didn't like the sound of that,
			sir. I've always known the risks
			that come with a Starfleet
			uniform. If I am to die in one,
			I'd like my death to count for
			something.

					PICARD
			Lieutenant...

          STAR TREK: "Yesterday's... " - 12/8/89 - ACT FOUR          48.

62   CONTINUED: (2)

	A long look, many feelings...

					PICARD
			Permission granted.

	She rises. Salutes him.

					TASHA
			Thank you, sir.

	And EXITS. A long beat on Picard and...

63   INT. ENTERPRISE-C MAIN BRIDGE

	The CREW is busy at work, closing up patched-together

			You're not part of my crew.

					TASHA
			I am now. Captain Picard approved
			my request for transfer.

66   NEW ANGLE

	as Castillo leads Tasha to one side -- not wanting to
	continue this discussion in front of the crew.

					CASTILLO
			This isn't a joke, Tasha. We're
			going back in the rift -- into
			battle -- and we're not coming
			back.

					TASHA
			I know the mission. These are
			my orders, Lieutenant.

					CASTILLO
			But I don't want you here.

					TASHA
			You need me. Show me someone on
			your crew that can do the job
			better than I can.

	Castillo knows he can't; there is no one as qualified.
	He looks at her with appreciation.

					CASTILLO
				(quietly)
			Welcome aboard.
				(then, louder, for the
				 crew)
			Take your station, Lieutenant.

	Tasha, all business, moves to her station.

					TASHA
			Aye, sir.

	As she runs a check on Tactical, we:

	Picard in command, studying the image of the

	Tasha ENTERS from turbolift.

					TASHA
			We've finished the transfer of
			equipment, Captain. The new
			converters should be able to
			compensate for the damaged units
			on the Enterprise-C.

	Picard stands, nods. Riker moves a couple of steps
	closer, while Wes and Data turn to look at Tasha. An
	awkward moment... too much to say... this is neither
	the time nor the place. Picard clears his throat, but
	before he can say anything there is a SOUND from the
	Ops panel. Data turns to his console.

					WESLEY
			Long-range scans have picked up

	Tasha looks around the bridge. Wesley manages a halfhearted

	Another HIT ROCKS the bridge.

									INTERCUT:

84   INT. ENTERPRISE-D MAIN ENGINEERING

	The room is filled with smoke and crackling consoles.
	SUPERNUMERARIES, some wounded or dead are in b.g.
	Geordi is trying to make his report through the
	confusion and damage.

					GEORDI
			Engineer to bridge. Can't hold
			the antimatter containment
			fields... Initiating emergency
			shutdown...

	TWO EXPLOSIONS go off in the Engine Core. An ALARM
	sounds just as a CLOUD OF GAS starts to pour out of
	the Engine Core. Geordi reacts with horror. (NOTE:
	computer registers a "force field failure" and the
	emergency isolation door descends to close off the
	engine core.)

					GEORDI
			Coolant leak! bridge, we have
			a coolant leak in the engine core!
			I can't shut it down -- estimate
			two minutes to warp core
			breach...

85   INT. ENTERPRISE-D MAIN BRIDGE

	Geordi is cut off in mid-sentence as the bridge is
	ROCKED again.

					PICARD
			How long until the Enterprise-C
			enters the rift?

					DATA
			Fifty-two seconds.

86   EXT. SPACE - ENTERPRISE-C AND RIFT (OPTICAL)

	The ship is just about to enter the rift.

87   INT. ENTERPRISE-D MAIN BRIDGE

					PICARD
			All remaining power to defense
			systems.

					DATA
			Power couplings severed in
			forward phaser banks. Attempting
			to by-pass.
				(works console)
			Controls not responding.

	A SHAKE as the ship is hit again. An EXPLOSION at
	Tactical. Riker goes down. Picard's face is grim.
	This is the end and he knows it. A Klingon voice is
	heard on the com (possibly Worf).

					KLINGON COM VOICE
			Federation ship Enterprise...
			surrender and prepare to be
			boarded!

	Picard looks defiantly at the ships on the viewer.
	He goes to the Tactical station and works the controls
	himself. He looks at the Klingons with steel in his
	eyes.

					PICARD
				(softly)
			Like hell.

	Picard fires the phasers.

          STAR TREK: "Yesterday's... " - 12/8/89 - ACT FIVE          58.

88   CLOSE ON PICARD

	holding on to the Tactical console as the ship is hit
	by phaser fire...

89   ON KLINGONS (OPTICAL)

	They press in closer for the kill and continue to FIRE
	at the Enterprise-D.

90   ON ENTERPRISE-C AND RIFT (OPTICAL)

	The ship enters the rift and disappears.

									CUT TO:

91   INT. ENTERPRISE-D MAIN BRIDGE - CLOSE ON PICARD

	Match shot on Picard as we last saw him. It is not
	immediately apparent whether or not anything has
	changed or if the battle is still raging.

					PICARD
			Report, Lieutenant.

92   NEW ANGLE

	which reveals the bridge of the Enterprise as seen in
	the Teaser. Everyone is back at their normal stations.
	The uniforms, the bridge itself and the people have
	returned to normal. Worf is back at Tactical; Troi
	is in her chair.

					WORF
			Readings fluctuated momentarily,
			Captain. It appeared to be a
			ship, but then it vanished.

	Picard takes this information in stride.

					DATA
			The rift is closing in on itself,
			Captain.

					PICARD
			Very well. Prepare a class-one
			sensor probe. We'll leave it
			behind to monitor the final
			closure. Mister Crusher, lay in
			a course for Archer Four.

92   CONTINUED:

	Business as usual. As if nothing ever happened...
	and to them it hasn't.

					GUINAN'S COM VOICE
			Guinan to Captain Picard... is
			everything all right up there?

	Picard is a little puzzled by this unusual
	communication from Guinan.

					PICARD
			Guinan?... Yes... everything's
			fine. Is something wrong?

93   INT. TEN-FORWARD

	Guinan is behind the bar, holding a drink she's just
	made.

					GUINAN
			No, sir. Sorry to bother you.

	She looks around. Everything is right. A sad smile
	crosses her features. She nods her head with
	satisfaction. FOLLOW her as she moves down the bar
	and hands the drink to Geordi.

					GEORDI
			Thanks, Guinan.

	Guinan nods, leans on the bar:

					GUINAN
			Geordi... tell me about Tasha
			Yar.

									FADE OUT.

                        END OF ACT FIVE
