THE TENTH PLANET

EPISODE 4

1.  TRACKING ROOM

(Ben lies on the ground, nursing a bruise on his head from General Cutler's blow.  Polly, kneeling next to Ben, tries nursing his wound.  Cutler is preoccupied with the launch of the rocket at Mondas.  Dyson and Barclay look on anxiously.)

POLLY:  .....succeeded in just a few seconds.
COUNTDOWN VOICE:  T-minus 20 seconds...  T-minus 15 seconds...  T-minus 10 seconds, 9... 8... 7... 6... 5... 4... 3... 2... 1... Blast off!

(The computer monitor's screen is temporarily obscured by the rocket's afterburn.  Suddenly, the afterburn clears and the rocket is revealed not to have taken off.)

POLLY:  Ben, you made it!  The rocket hasn't gone off, it didn't work!  Now we've all got a chance of life!

(The General is enraged.  He turns to Ben and Polly.)

GENERAL CUTLER:  Your Cybermen friends may have a chance of life, but not you, sailor!

(He looks at the unconscious Doctor.)

GENERAL CUTLER:  Nor that old man.  Now go get him up here.
POLLY:  But he's ill!
GENERAL CUTLER:  He's gonna get worse.  Get him up!

(As he speaks, the Doctor recovers and speaks weakly to Cutler.)

DOCTOR:  No need...  I'm here.
BEN:  Doctor, you alright?
DOCTOR:  Yes, yes, yes...
(to General Cutler)  Your plan is foiled, sir.  You cannot fire the rocket!
GENERAL CUTLER:  You just arrived in time... get over there.
DOCTOR:  I must protest!
GENERAL CUTLER:  Move!

(Cutler turns around and sternly addresses Dyson.)

GENERAL CUTLER:  Dyson, get through to Zeus 5!

(With the General's attention drawn elsewhere, Polly moves over to the Doctor.)

POLLY:  What's happened to you, Doctor?
DOCTOR:  I'm not sure, my dear.  Comes from an outside influence.  Unless this old body of mine is wearing a bit thin.
POLLY:  What do you mean "wearing a bit thin"?
DOCTOR:  Oh, don't worry child, don't worry, don't worry...  Oh, let's have a look, dear boy, eh?...

(The Doctor rises to his feet.  He, Ben and Polly move over behind General Cutler, who is pointing a pistol at Barclay's head.  Barclay sits watching him calmly.)

GENERAL CUTLER:  Barclay... that rocket was sabotaged with your help.  Now you're gonna get it off the ground again.  I'm gonna give you one more chance or you're gonna get killed with them.
BARCLAY:  I can't fire this rocket, and neither can you.
GENERAL CUTLER:  How long will it take you to refuel?
BARCLAY:  Long enough!
GENERAL CUTLER:  Alright, if that's the way you want to play it... get up.  Get up!  Get over there!

(He motions Barclay over to the wall, with the Tardis crew.)

DYSON:  I'm getting a signal, sir. From Lieutenant Cutler, sir.

(Lt. Terry Cutler appears on Dyson's monitor.  The General moves over to listen to his son.)

TERRY CUTLER:  I'm tumbling badly and there's little control left in the capsule - I must speak fast!
GENERAL CUTLER:  Yes, go ahead, son!
TERRY CUTLER:  This new planet, there's something strange happening.
GENERAL CUTLER:  What do you mean?
TERRY CUTLER:  Well it seems to brighten up like a sun and then darken again.

(The Doctor has been listening, and adds to Terry Cutler's remarks.)

DOCTOR:  It cannot absorb much more energy!

(Nearby, a radar technician notices blips on his radar.)

RADAR TECHNICIAN:  Sir, Cyberman spaceships on approach path.
GENERAL CUTLER:  Shut up, will you?  Go ahead, son.

(The General is growing increasingly agitated.  Lt. Cutler's signal is becoming weaker by the second.)

TERRY CUTLER:  Hey... controls gone again... energy loss severe...  It's like... it's like being on a switchback...  I ca- I can't seem to -

(The image on the screen cuts out, and there is a disturbing silence as the static fades away.)

GENERAL CUTLER:  Get that signal back!
DYSON:  It's gone... could be a power failure.

(The General starts to show even more signs of panic and strain.)

GENERAL CUTLER:  Come on, man! Come on, Dyson, get that signal!
RADAR TECHNICIAN:  Sir, Cyberman ship on descent now!

DYSON: Radio____. Hopeless.
BARCLAY:  The enemy will landing at any moment.

DOCTOR: General!

(For the first time, General Cutler seems to lose control.  His face is sweating and his shoulders are slumped forward.)

GENERAL CUTLER:  The enemy!  The enemy!  I'll tell you who the enemy is.  You are the enemy!

(He turns to face the Doctor.)

RADAR TECHNICIAN:  The Cybermen sir, they must have landed!
GENERAL CUTLER:  You..you..you..you killed my son.
RADAR TECHNICIAN:  But sir, they've landed!

(General Cutler is oblivious to the warnings.  He rounds upon Barclay, the Doctor, Ben and Polly with his pistol drawn.  All the technicians in the room scatter for cover.  Cutler points his gun at the four.)

GENERAL CUTLER:  My son! The only person I gave a care about in this whole world, and you killed him.  So now I'm going to kill you... and I'll start on you, Doctor!

(The crack of rifle shots is heard from outside the room, followed by the whine of Cyber-weapons.  Polly begins to scream.  The whine of the Cyber-weapon is heard again.  General Cutler spins around to see a Cyberman standing in the doorway!  He shoots a bullet into the Cyberman's front armour, only to see it ricochet harmlessly.  The cyber-weapon whines again, and this time is followed by silence.  There is a horrified look on the General's face, and smoke begins to pour out from his collar.  He slumps to the ground, dead.  The Cyberman casually walks into the room, followed by two others.  The men in the room stand frozen like statues.  The Doctor steps forward; immediately the lead Cyberman swings around to face him, weapon levelled.)

KRANG:  Silence.  Anyone who moves will be killed instantly.

(The Doctor turns and points to Barclay, Ben and Polly.)

DOCTOR:  We owe you our lives.  That man was going to have us shot.

(He points to the body of General Cutler.  Krang, the new Cyberleader, ignores the Doctor and gestures to the guards with his Cyber-weapon.  Without hesitation, the guards obey, tossing down their guns and raising their hands.  Krang points at the Doctor and his friends.)

KRANG:  Go with the others down there.

(The Doctor, Ben, Polly and Barclay join the guards and base technicians.)

BEN:  There's gratitude for yer!  We save their grotty planet Mondas for what?

(Krang turns around and looks at the Doctor and Ben.)

KRANG:  Saved Mondas?  We do not believe you.  We have seen a rocket missile aimed at Mondas.
DOCTOR:  That is so.  We prevented it being fired at you.  We helped you.  Therefore, I suggest you help us.
BEN:  It's no use talking to these geezers.

(Krang raises his hand for silence.)

KRANG:  And what do you ask in return for this?
DOCTOR:  Your planet is finished.  It will disintegrate.  We know why you came here.  So why not stay and live with us in peace, hmm?
KRANG:  We will confer.  Keep your places.  Anyone who moves will be killed instantly.

(Krang walks over to the other two Cybermen in the room to discuss the proposal.)

BARCLAY:  Can we trust them?
BEN:  No, of course we can't.
DOCTOR:  We have no chance.  We must play for time.  Be quiet!

(The Doctor advances towards Krang.)

DOCTOR:  Well sir, what have you decided?
KRANG:  We cannot talk while that missile is aimed at Mondas.  It must be disarmed first.
DOCTOR:  A moment, please.

(He turns to Barclay.)

DOCTOR:  Are you able to disarm this rocket?
BARCLAY:  Well, yes - but...
DOCTOR:  It will give us the time we need!
BEN:  The time for Mondas to burn itself out, you mean?
DOCTOR:  Yes, now quiet!
(to Krang)  We accept your terms.  The warhead will be removed from the rocket.
KRANG:  It must be removed to below ground level.
BARCLAY:  Well, there's the Radiation Room.  It's the deepest in the base.
KRANG:  That will do.  And to make sure you do this, we will take two hostages.

(He points to Polly.)

KRANG:  That girl will go to the spacecraft.

(He then turns to the Doctor.)

KRANG:  You will stay here with us.
(to Ben, Dyson and Barclay)  You three must go to the rocket.
DOCTOR:  You must do as they say.

(Ben approahes the Cybermen.)

BEN:  Look, if you want a hostage, what about me?
KRANG:  You are needed to help with the warhead.
BEN:  Now look here, you're not taking Polly!
DOCTOR:  Let me handle this, my boy!
BEN:  But Doctor...
DOCTOR:  All of you - go with Barclay.
BARCLAY:  But Doctor, I do think that...
DOCTOR:  Go.  I think it is wiser.
BARCLAY:  Very well.  Come on Dyson.

(The Doctor walks towards the Cybermen and addresses Krang.)

DOCTOR:  You give me your word that this young girl will be returned to me when that bomb is safely stored away?
KRANG:  Yes.
DOCTOR:  Very well, child, off you go.  And don't forget your coat, I don't want you to get cold!

(One of the Cybermen leaves the Tracking Room with Polly.)

2.  INTERIOR, CYBERMAN SHIP

(Inside the Cybership, Polly's captor places her in a chair-like cage.  The barred front of the cage is closed, trapping her.)

POLLY:  Ow!  What are you going to do with me now?  What kind of chair is that?  It's horrible!  Look, keep back!  Keep away from me!

(Without replying, the Cyberman moves closer.  He presses a button on his chest unit; a flash of light shoots from his helmet, and Polly falls unconscious.  As she sleeps, the ship begins to warm up.  She is being kept alive... for now.)

3.  TRACKING ROOM

(A video message is coming through from International Space Command Headquarters in Geneva.)

SECRETARY:  (on monitor screen)  Geneva calling South Polar base.  Geneva to South Pole.

(The Doctor looks at Krang.)

DOCTOR:  Didn't you hear?

(The message continues to echo throughout the Tracking Room.)

SECRETARY:  Geneva calling South Polar base.  Geneva to South Pole.  Geneva to South Pole.  Geneva to South Pole.

(The two Cybermen order the Doctor to answer the call.)

DOCTOR:  Hello Geneva, Geneva...
SECRETARY:  Secretary Wigner to speak with General Cutler.

(The Doctor looks a bit awkward.)

DOCTOR:  I'm afraid the General isn't here at the moment... and I... I've been put in charge temporarily.
WIGNER:  Who is that speaking?
DOCTOR:  I have no time to discuss it now, sir.
WIGNER:  Tell General Cutler there have been mass landings of Cybermen in many parts of the world.  Who are you?

(As Wigner speaks, the Geneva base is stormed by Cybermen.  After a moment's silence, a harsh, metallic Cyberman voice is heard over the monitor from Geneva.)

GERN:  (to Wigner)  I am now Controller of the Earth.  Resist us and you die.

(Gern turns and talks into the monitor link.)

GERN:  You must proceed with your second objective.

(Krang orders the Doctor to move, and sits down in Barclay's chair.  He leans forward to speak into the microphone.)

KRANG:  We are proceeding according to plan.
GERN:  (on monitor)  Report to me as soon as you are ready.  We must have time to evacuate.

(Krang addresses the Cybermen in the South Pole base via the microphone.)

KRANG:  Unit Delta plus calling.  Unit Delta plus calling.  Unit Delta plus calling.

(The Doctor rises and approaches Krang at the controls.)

DOCTOR:  I do not understand your friend, sir.  Evacuate?  Surely you're not going to return to Mondas now?
KRANG:  We will not discuss our plans with you.
DOCTOR:  (angrily)  What is your second objective?  It's quite obvious, isn't it?  The destruction of the Earth!

(He grabs the microphone and speaks into it.)

DOCTOR:  Ben!  Barclay!  Do not help them.  They're going to use the Z-bomb to destroy the Earth!

4.  RADIATION ROOM

(Ben, Barclay, Dyson and Haines, a technician, are all clothed in protective radiation suits.  They hear the Doctor's warning, and watch events in the Tracking Room on a monitor link by the door.)

BEN:  Did you all hear that?
BARCLAY:  Of course, it all makes sense now!  We've allowed ourselves to be fooled by them!
DYSON:  We've just set them up nicely.  Cutler was right, wasn't he?  We should have used the bomb on them.
BARCLAY:  No, that might quite easily have led to something far worse.
DYSON:  Worse?  We're just about to be blown to bits along with the entire population of the Earth, and you talk about something worse?
BEN:  Give over, mate!  What he means is, while there's life there's still hope.
DYSON:  Seems to me we've just signed our own death warrants.

(A Cyberman is on guard outside the room.  Krang can be heard over the monitor giving orders to the Cyberman.)

KRANG:  (on monitor)  Check progress on the bomb.
BEN:  Quick!  All look busy!  Bring in number two line!

(They pretend to be working as the Cyberman walks past the door.)

BEN:  'Alf a mo'.  The Doctor told us to play for time, right?  And I've got an idea.
DYSON:  Marvellous.
BEN:  Well, might at least hear it!  I don't hear any bright suggestions coming from you two guys!
BARCLAY:  Go on.
BEN:  Well, any idea how strong these Cybermen are?
BARCLAY:  A rough idea.
BEN:  Yeah, well they could lift a man like he was... well, like he was a wrench, right?
DYSON:  Yes, well?
BEN:  Well they're also pretty advanced geezers, way ahead of us.
DYSON:  What has this got to do with it?
BEN:  Well, that just it.  With all this, why should they need us?  Well, they could shift that bomb in half the time!  So why get us to do it?  Also, you'll notice they remain outside this door, looking at us all the time through the door.  Well why?
DYSON:  This is just a waste of time.
BARCLAY:  Now wait a minute, I think I see what he's driving at.  They use us because they daren't handle it themselves.
BEN:  Yeah, but the point is, why?  Well you're the scientists.
BARCLAY:  Don't you see, Dyson?  It could that they're afraid of radioactivity.
BEN:  Let's get this one inside and see what it does to him.  Now look... all lie down on the floor... play dead.
DYSON:  This is ridiculous... games.
BARCLAY:  Well may be, but it's worth giving it a try.  Come on, lie down.

(Barclay, Dyson and Haines lie on the floor, as Ben stands by the door and shouts to the Cyberman guard.)

BEN:  Help!  Help!  Come in here, mate, there's something up!  Help!

(Ben feigns collapse as the Cyberman peers carefully through the small door portal.  It then opens the door and slowly walks into the room.  After only a few steps the Cyberman stops dead and drops its Cyber-weapon.  Ben shoves the large metallic body out of the room and locks the door.)

BEN:  You see?
DYSON:  What did you do that for?  We could have escaped!
BEN:  To where?  We're okay right where we are.
BARCLAY:  And they can't set off this bomb while we defend this room!
BEN:  Right!  So all we've go to do is sit tight until Mondas breaks up like the Doctor said!  Well, we've got them!  But they've still got the Doctor and Polly.

5.  TRACKING ROOM

(After witnessing the events in the radiation room over the monitor link, the Doctor turns to Krang.)

DOCTOR:  Well gentlemen, stalemate I think, don't you agree?  Well now, what about a little talk, hmm?
KRANG:  You forget we can do what we like with all of you and the girl.
DOCTOR:  Oh, quite so, but I'm afraid that won't help save your planet.

(Krang turns to the monitor and addresses the Radiation Room.)

KRANG:  Listen to me.  This close proximity of our two planets means that one has to be eliminated for the safety of the other.  The one to be destroyed will be Earth.  We cannot allow Mondas to burn up.

6.  RADIATION ROOM

KRANG:  (on monitor)  If you help, we will take you all back to Mondas with us.  There you will be safe.
BEN:  Yeah?  For how long?
DYSON:  It could be our only chance.
BEN:  The answer is no!  We'll just sit tight here until Mondas breaks up.  Now then, you'd better release the Doctor and Polly and send them down here.  You're gonna need our help when Mondas is gone!

7.  TRACKING ROOM

(Krang listens to Ben, and watches Mondas's condition on another monitor screen.)

KRANG:  Mondas will not burn up.

(He turns to another Cyberman.)

KRANG:  Take the old man out to the spacecraft.
DOCTOR:  You will regret this.

(Krang addresses the captives in the Radiation Room.)

KRANG:  Now we give you three minutes to start fusing the warhead.  If you fail, you will never see your friends again.

(The second Cyberman grabs hold of his Cyber-weapon and escorts the Doctor out of the Tracking Room.)

8.  RADIATION ROOM

(As Krang finishes his ultimatum, Ben turns from the monitor screen to face the others.)

BEN:  ...... Really done it.  What do we do now?
DYSON:  This is hopeless... we must do as they say!
BARCLAY:  Well, it could be a bluff.
BEN:  Yeah, how do we find out?
BARCLAY:  We must stick to our plan and sit tight.  There are millions of lives at stake.
BEN:  Yeah, but there must be something we can do!

(Ben turns to the monitor screen and smashes it.)

DYSON:  What did you do that for?  Now we can't communicate with them.
BEN:  No, and they can't spy on us either.  Now this is what I think we should do.

9.  CYBERMAN SHIP

(On board the Cybermen's craft, the Doctor and Polly are imprisoned together; the Doctor is in another chair-cage next to Polly.  Both have their hands bound.)

POLLY:  Doctor...  Doctor?

(The Doctor barely has enough energy to raise his head to reply.)

DOCTOR:  Hmm...  What is it, child?
POLLY:  Engines!  They're not going to take off, are they?

(The Doctor listens to the low, throbbing background vibration.)

DOCTOR:  No, no.  Wait!  The vibrations.  Perhaps it's coming from Mondas!
POLLY:  What do you mean, Mondas?
DOCTOR:  This spacecraft receives its energy from Mondas.  Perhaps it's absorbing too much.
POLLY:  Don't mean it's going to blow up, do you?
DOCTOR:  No, I don't know, child.  It is an unknown power...
POLLY:  Doctor, I'm scared!

10.  RADIATION ROOM

(Ben is examining a large machine which holds a number of radiation rods.)

BEN:  What's it weigh then?
DYSON:  You're not thinking of carrying that thing around with you, are you?
BEN:  I'm not asking you.  Can it be shifted, Dr Barclay?
BARCLAY:  No, it would be an impossible task to use it as you intend using it.
BEN:  Well, just what is there in this room that is radioactive and that a bloke could carry?
DYSON:  Nothing.  You're wasting your time and ours.  And our three minutes is nearly up, anyway.
BEN:  You think so.

(He points to a panel in the wall of the room.)

BEN:  Is there anything behind here that is radioactive?
BARCLAY:  Well yes, of course.  That's the base nuclear reactor.  It supplies all the power.
BEN:  Well what's it like?  Is there anything that could be moved by hand?
BARCLAY:  Well, if we extracted the reactor rods they could be carried for a short distance but it would be a very tricky operation.
BEN:  Well, it's our only hope.  Come on!
DYSON:  Are you both quite mad?
BEN:  Look, Dyson, we're the sane ones.  Do you really think those Cybermen intend to let us live?
DYSON:  They gave us their word.
BEN:  They just said anything they thought we'd listen to.  They've got no feelings, remember?  They told us that.  So what's to stop them?  Anyway, you might as well face it, mate - your number's up either way.  So why not try, eh?  We need your help anyway, okay?

11.  TRACKING ROOM

(Krang and Jarl, the second Cyberman, wait for the three minutes to pass.  They watch impassively as the monitor screens are filled with the globe of the planet Mondas.  The planet is violently alternating between light and dark.)

JARL:  Records, Krang.
KRANG:  Our planet is nearing saturation point. We must lose no time. Switch on the monitor.  Their three minutes is up, we must hear their decision.

(Jarl tries turning on the Radiation Room monitor, but it doesn't work.)

KRANG:  What has happened?

12.  RADIATION ROOM

(Ben and Haines are extracting the fuel rods from the reactor.)

BARCLAY:  Hold them away from yourselves.  Gently does it, very gently. Stand by the emergency power switch. The lights will be fading any second now.
DYSON:  I suppose you realize there's only about an hour's supply of lighting and heating in the emergency batteries. Then we shall all freeze to death.
BEN:  If this don't work, mate, you needn't worry about the cold anymore.

(He opens the reactor room door slightly and walks out into the corridor.)

BEN:  Okay, it's all clear.  Quick!  Dyson, you go up this end of the corridor.  When you hear the Cybermen coming, come out behind them.  Haines, you go round that corridor and do the same.  Now look, I'll draw their fire, so when you hear the sound of this gun, start coming forward.  (looking at the rods)  Do you really think there's enough radiation in these two rods to trap them?
BARCLAY:  Just.
BEN:  Okay, come on.

13.  CORRIDOR

(Krang, Jarl and a third Cyberman are advancing to the radiation room.  Ben watches them from around the corner.)

KRANG:  Do not use this gas unless you have to.  We need them alive and conscious.

(Ben retreats to the others in the Radiation Room.)

14.  RADIATION ROOM

BEN:  They're coming.  Quick!  Behind the door.

15.  CORRIDOR

(The Cybermen come to the door to the Radiation Room.  Jarl addresses the men inside.)

KRANG:  Your three minutes is up.  What is your decision?

(There is no reply.)

KRANG:  We shall be forced to kill you.  We will give you one more chance to come out and give us the bomb.
BEN:  (oov, from inside the room)  Come in and get it!

(Krang nods to the third Cyberman, who starts to pour gas into the reactor room through the crack in the door.)

16.  RADIATION ROOM

(As smoke pours into the room, Barclay starts to cough.  Ben runs over to the far wall and levels the Cyber-weapon the Cyberman had dropped previously.)

BEN:  There's something else down by the door!

(Barclay opens the door wide.)

BEN:  Now!

(Without aiming, Ben fires his Cyber-weapon into the thick gas, where he can only just see the outline of the Cyberman holding the cylinder.  The Cyberman drops the gas cylinder, raises his hands up in the air, and staggers back.  Krang and Jarl pull the door shut to prevent any further shots.)

BARCLAY:  I can't hold out much longer!
BEN:  Where's Dyson and the other bloke got to?

17.  CORRIDOR

KRANG:  The humans are behind the door.  Let the gas do its work.

(As he speaks, Haines and Dyson approach from either end of the corridor.  The radioactive rods they are holding cause the Cybermen to stagger and lose control.  As the two men come closer, both Cybermen collapse and lie still.  Ben calls out from inside the radiation room.)

BEN:  Quick, Dyson!  Help get Barclay out of here!

(The two men pull Barclay clear of the gas, and they head back to the Tracking Room.)

18.  TRACKING ROOM

(The room is a hive of activity, with technicians reclaiming control of the base.  Barclay speaks to a technician.)

          DYSON:  Back to your desks all of you. The emergency's not over yet. Philips, there are two reactor rods in the corridor.  See that

          they're put back at once.

BEN:  Hey, they've still got the Doctor and Polly.
BARCLAY:  No, wait!  If you try and tackle the spacecrafts on your own, you don't stand a chance.  We don't know how many Cybermen there are left.
BEN:  Well?

(He indicates a small piece of Cyber-machinery on the floor.)

BARCLAY:  Well, here's one of the things they use to contact each other.
BEN:  I don't know how it works.
BARCLAY:  Well then do anything, make a signal!  Draw them here.
DYSON:  Is that wise?
BEN:  Well, if that spaceship takes off we'll never gonna see them again.
DYSON:  You may bring them all in on us!
BEN:  Well that's a risk we've got to take.

(He begins to fiddle with the contraption, which starts making a buzzing sound.)

BEN:  That should do it.  Any idea how long it'll take for them to get here?
DYSON:  You stand by with those guns.
BARCLAY:  Now look, we must all get down by the other side of the room.
BEN:  Okay.
BARCLAY:  Opposite the door so we can face them.  Use the guns.

(The lights go out.)

BEN:  What now?
DYSON:  The emergency battery's running out, I suppose.
BARCLAY:  We can't face them in the dark!
DYSON:  Now we shall freeze to death.
BARCLAY:  They must get those reactor rods back.

BEN:  Hang on, they're coming back. (As the lights come back on)

(Ben looks through the doorway and sees the Cybermen advancing.)

BEN:  Look!

(Just outside the Tracking Room, Krang addresses the humans.)

CYBERMAN:  Resistance is useless.  Drop your weapons.

(Just then, Ben looks up at the monitor screen showing the planet Mondas.)

BEN:  Just look at Mondas!  I can't believe it!

(Everyone turns to look at the screen.  The planet is alternating from light to dark much faster now, and the planet starts to distort.  As they watch, huge fissures and cracks appear in the surface.  Streams of white-hot lava run from the cracks and spread over the face of the planet.)

DYSON:  Fantastic!  It looks as if it's melting!
BEN:  It's falling to bits!
BARCLAY:  The end of Mondas.
BEN:  Hey, look!

(In the excitement, the Cybermen in the room have almost been forgotten.  Like their planet, the Cybermen are changing visibly.  Their arms drop; the Cyber-weapons fall to the floor; each teeters slightly on his feet.  They slowly collapse down on one knee, then the other.  Finally they pitch forward on the floor, and are still.  The corpses begin to disintegrate, leaving just the crumpled silver outer shells.)

BEN:  What's happened to them?
BARCLAY:  They've disintegrated!
DYSON:  They must have been entirely dependent on power from Mondas!

(They turn back to the monitor.  The planet is now a huge corona of gas surrounding the few remaining solid segments.  As they watch, the distorted flare of gas that was once the Tenth Planet grows fainter and fainter as it spins away from the Earth.  As Mondas disappears, the R/T system crackles back to life.  The voice of Terry Cutler can be heard.)

TERRY CUTLER:  (oov)  Zeus 5 to Snowcap, are you receiving me, over?
BARCLAY:  Quick Dyson, get that!

(Dyson runs over to the communications system.)

DYSON:  Snowcap to Zeus 5, reading you loud and clear.

(Terry Cutler's face appears on the monitor.)

TERRY CUTLER:  What happened?  Where have you been?

(Barclay moves over next to Dyson.)

BARCLAY:  (to Dyson)  Here, let me have that.  (to Cutler)  Snowcap to Zeus 5, what is your fuel position?
TERRY CUTLER:  It's okay, everything's suddenly working normally.  And what about getting me down?
BARCLAY:  We've been on emergency power.  We'll handle your splashdown as soon as we get full power back.  (to Dyson)  Start checking the base main units.
DYSON:  Yes, right.

(Barclay uses the communications system to contact Geneva.)

BARCLAY:  Hello Geneva?  Geneva?

(Just then, Ben remembers his travelling companions.)

BEN:  Hey!  The Doctor and Polly!
BARCLAY:  Snowcap here.

(The monitor switches to a picture of the Geneva office.  Wigner sits at the desk, with a secretary beside him.)

WIGNER:  Hello Snowcap, who is that, Barclay?
BARCLAY:  Yes, we've just getting full power back.  The danger is apparently over.
WIGNER:  The Cyberman menace has ended all over the world!  Let me have a full report as soon as you can.
BARCLAY:  Sir, will do.  Did you hear that?  He wants a full report.  Where exactly shall we begin, do you think?

(In the general excitement, Ben is not noticed as he leaves the room.)

19.  CYBERMAN SHIP

(Ben arrives in the containment room of the Cybership, where the Doctor and Polly are still imprisoned.)

BEN:  Doctor!

(The Doctor is motionless.)

POLLY:  Ben!  Oh please, Ben, help me... get me out of this thing!
BEN:  All right, don't panic, I'll have you out soon!

(Ben opens the cages holding Polly and the Doctor.  Polly immediately leaps up, but the Doctor still does not move.)

POLLY:  Ow!  My hands were stuck and I couldn't get out!...  Ben, I've been so scared!
BEN:  Take it easy love, take it easy.
POLLY:  And that Cyberman thing, it just fizzled into nothing, Ben, it was awful...

(Ben looks over at the Doctor.)

BEN:  Now what's the matter with the Doctor?
POLLY:  I don't know.  When the lights went out, he just seemed to faint.

(Ben bends down in front of the Doctor and snaps his fingers.)

BEN:  Hey, come on Doctor, wakey wakey!  It's all over now.

(The Doctor shakes his head.)

DOCTOR:  What did you say, my boy?  "It's all over."  "It's all over."  That's what you said.  No... but it isn't all over.  It's far from being all over.
BEN:  What are you taking about?

(The Doctor has a glazed, distant look on his face.)

DOCTOR:  I must get back to the TARDIS immediately!
POLLY:  Alright, Doctor.
DOCTOR:  Yes...  I must go now.
BEN:  Aren't we going  to go back to say good-bye or anything?
DOCTOR:  No!  No, I must go at once.

(Polly offers a helping hand, but the Doctor refuses it, brushing quickly past.  Ben holds out his scarf.)

BEN:  Oh well, you better have this.  We don't want you catching your death of cold.
DOCTOR:  Ah, yes!  Thank you.  It's good.  Keep warm.

(The Doctor leaves without waiting for his companions.  Polly whispers to Ben.)

POLLY:  What's happened to him?
BEN:  Dunno.  He seems to lost his sense of humour.
POLLY:  Well I can't wait to get out of here!

(They walk through the Cyberman craft towards the exit.  Ben looks at some fallen Cybermen as they go.)

BEN:  Good looking guys, ain't they?

(Outside, the Doctor battles through the snow, followed some distance behind by Ben and Polly.  The Doctor stops in front of the TARDIS and opens the outer doors.  He enters, and the doors shut just as Ben and Polly arrive.)

POLLY:  Wait for us!
BEN:  Open the door!
POLLY:  Hey, let us in!
BEN:  You can't leave us here, of all places!  Open up!
POLLY:  Doctor!

21.  INTERIOR THE TARDIS

(In the control room, the Doctor is clearly weakening.  He leans against the console and operates the door control; Ben and Polly burst in to see him stagger past the console and lean forward.  The TARDIS controls are now working themselves; the door closes and the central column begins moving up and down.  The Doctor's body is wracked by some huge inner turmoil; he struggles to stay on his feet, but the effort is too much for him.  He collapses.)

POLLY:  Doctor!  Quick, help him!
BEN:  No, leave him!

(Ben points at the unconscious Doctor.  The old man is lying on his back, totally still, his face expressionless.  As they watch, a strange glow comes over the Doctor's face; the glow brightens to a brilliant white, then fades.  And the face which is left behind is that of a total stranger...)
