Episode Four
First Air Date: 18 January 1975
Running time: 24:29
BRIGADIER: Well, I brought along something that will deal with it.
DOCTOR: I very much doubt it, Brigadier.
ROBOT: Go! Go now, or I will destroy you all.
WINTERS: Well, everything seems to be very satisfactory. And how are you getting on, Professor?
KETTLEWELL: I've just finished making the preliminary linkups. You don't really intend to use the destructor codes, do you?
WINTERS: I want everything in readiness.
KETTLEWELL: But if they don't agree, if they call our bluff, we'll surrender, won't we?
WINTERS: No. We shall fire the missiles.
KETTLEWELL: But you can't. It would mean a nuclear w*r.
WINTERS: You want a better world, don't you? We shan't gain it without some sacrifices. Now, start the countdown, Professor.
HARRY: How are we doing, Miss Smith?
SARAH: Okay.
HARRY: Yeah, I think it's coming.
WINTERS: What about food and water? How long can we hold out if the worst happens?
JELLICOE: I'm not really sure.
WINTERS: Then you should be. Take me to the food storage. We must make a proper check. (To KETTLEWELL.) Keep your eye on our friends outside, Professor.
JELLICOE: Wait.
JELLICOE: What are we going to do with them?
WINTERS: They're obviously no use to us as hostages. We can't afford useless mouths to feed. They'll have to be disposed of. Later.
HARRY: That was a near one.
SARAH: We're nearly there, I think.
HARRY: Yeah.
SARAH: Okay.
BRIGADIER: What's the range and power of that w*apon, Doctor?
DOCTOR: Power? Almost unlimited. Range, well, it could drill a hole in the surface of the moon.
BRIGADIER: And knock out anything we send against it.
DOCTOR: Yes. Well, it's no use staying here. Brigadier, prepare your men for an att*ck. Try and draw the robot away from the door. I'll slip around behind it and finish cutting the lock.
BRIGADIER: You don't stand much chance, you know.
DOCTOR: I know, but we have to try.
BRIGADIER: Right. We'll cover you as long as we can. All right, Benton?
KETTLEWELL: Can't... I won't.
JELLICOE: Don't attempt to stop it.
KETTLEWELL: No, I can't do. I won't do it!
JELLICOE: Let it run!
KETTLEWELL: Thank heavens you've come.
SARAH: Can you cancel what you've been doing?
KETTLEWELL: There's no time. I'll punch in the hold signal.
HARRY: So, now open the main doors. We're going outside.
KETTLEWELL: Yes.
SARAH: There.
HARRY: All right.
DOCTOR: Wait. The doors. Sarah.
SARAH: Doctor! (To the ROBOT.) Look, please don't sh**t. We're no danger to you.
ROBOT: You must go. The soldiers must go.
SARAH: You've got to let him in there.
ROBOT: They are enemies of the human race.
SARAH: No, they're the enemies in there. They want to start an atomic w*r. k*ll millions of people!
ROBOT: You must go or I will k*ll... I must k*ll you. I must destroy you.
KETTLEWELL: No, no! He was only telling...
ROBOT: I have k*lled the one who created me.
DOCTOR: Now's our chance.
BRIGADIER: Get away from that keyboard.
WINTERS: You won't sh**t, Brigadier.
SARAH: Maybe he won't, but I will. Move away!
WINTERS: Why not? It's finished. The f*ring instructions have gone out.
BRIGADIER: I can still get the major powers to use their fail-safe procedures.
WINTERS: Too late, Brigadier.
BRIGADIER: Cancel the destructor codes!
WINTERS: When that reaches zero, the missiles will be fired, and no one can send the cancel codes in time.
DOCTOR: She may be right, Brigadier.
BRIGADIER: Benton, get them both out of here.
BENTON: Miss Winters.
BRIGADIER: Go!
DOCTOR: The trouble with computers, of course, is that they're very sophisticated idiots. They do exactly what you tell them at amazing speed, even if you order them to k*ll you. So if you do happen to change your mind, it's very difficult to stop them obeying the original order, but... not impossible.
HARRY: Congratulations, Doctor.
SARAH: Oh, you've done it!
BENTON: Well done, Doctor.
BRIGADIER (OOV.): Right, that's over. Now for a little mopping up.
BENTON: Right, sir.
BRIGADIER: Vanished? How can they have vanished?
BENTON: We were all pretty busy inside, sir, mopping up the rest of that Thinktank lot. We noticed the robot was gone when we came out and everyone assumed that someone else had got it.
DOCTOR: And Sarah?
BENTON (OOV.): Well, we thought... We thought she'd gone home.
DOCTOR: Gone home? You mean not one of you connected the disappearance of Sarah with the vanishing of the robot?
BRIGADIER: You're sure there is a connection?
DOCTOR: I think so. Don't you?
HARRY: Why Sarah?
DOCTOR: The robot k*lled Kettlewell, remember? The man who created it. It must be in a state of tremendous emotional shock. What more natural than it should turn to the one person who ever showed it kindness?
BRIGADIER: Hmm. Keep looking, Benton.
BENTON: Right, sir.
SARAH: Honestly, they're bound to find us.
ROBOT: Anyone who finds us will be destroyed.
SARAH: Why? What's the point of more k*lling? I keep telling you, it's all over. What can you do alone?
ROBOT: I can bring about the destruction of humanity. But do not fear, Sarah. You alone will be saved. The bunker is cleared. Come.
DOCTOR: Well?
BENTON: Still nothing, sir. We're spreading the search radius wider and wider, but the bigger the area to cover, the harder it gets.
DOCTOR: There is just one teeny-weeny little thing.
BRIGADIER: What's that?
DOCTOR: Something else you haven't thought of. What are we going to do with it when we find it?
BRIGADIER: Yes. You know, just once I'd like to meet an alien menace that wasn't immune to b*ll*ts.
BENTON: Excuse me, sir.
BRIGADIER: Hmm?
BENTON: Well, when Professor Kettlewell was here talking to Miss Smith, he said the robot was made of some kind of living metal. He even said it could grow.
DOCTOR: Did he now?
BENTON: Yes. And he went on about some kind of metal virus. Something that att*cked the living metal.
DOCTOR: The same way disease att*cks animal tissue.
BENTON: Well, something like that. Anyway, I just wondered if we could...
DOCTOR: Yes?
BENTON: I'm sorry. It was probably a daft idea, anyway.
DOCTOR: Wonderful, Mr. Benton! Wonderful! Brigadier, I must get to Kettlewell's place at once. You find the robot.
BRIGADIER: (To HARRY.): You better go with him.
HARRY: Right, sir.
BRIGADIER (To HARRY.): Keep in RT contact.
SARAH: No! Don't hurt him! Let him go! He's not important enough. (To the SOLDIER.) Don't sh**t. Just leave now. Don't worry about me. Just go.
BENTON: Look, sir!
SARAH: No! No! Why? Why?
ROBOT: I destroyed Kettlewell. I must see that his plan does not fail.
SARAH: But... But he changed his mind. He wouldn't want you to continue.
ROBOT: Mankind is not worthy to survive. Once it is destroyed, I shall build more machines like myself. Machines do not lie.
DOCTOR: Why didn't that silly man write up his experiments properly?
BRIGADIER (OOV.): Doctor, this is the Brigadier. Can you hear me?
HARRY (On the phone.): This is Lieutenant Sullivan, sir. The Doctor's rather busy at the moment.
DOCTOR (To HARRY.): Tell him to stop pestering me. I've found a metal virus and I'm trying to prepare an active solution but he must give me time.
BRIGADIER (On the phone.): Sullivan, tell the Doctor we've found the robot.
HARRY (OOV.): Well done, sir. Where is it?
BRIGADIER (On the phone.): It's shut itself inside the bunker with Miss Smith.
DOCTOR: Yes! Yes, of course! Suppressed Oedipus complex, leading to excessive guilt and overcompensation.
BRIGADIER (OOV.): Doctor, Oedipus is not...
DOCTOR (On the phone.): Brigadier! The robot will try to carry out Kettlewell's plan. Is the computer terminal in the bunker still active?
BRIGADIER (OOV.): Far as I know. I don't suppose...
DOCTOR (On the phone.): Can you switch off the electricity supply?
BRIGADIER (OOV.): Yes... No, no. It's on a special sealed-circuit.
DOCTOR (On the phone.): Then warn all the major powers. The emergency is not over. They must operate full fail-safe procedures at once.
SARAH: Yes! You see, they've operated the fail-safe mechanism. Give up now. Please!
ROBOT: Humanity must be destroyed. It is evil. Corrupt.
SARAH: But you can't take on the whole world. Don't you understand? They'll destroy you.
ROBOT: Do not fear. I cannot be destroyed. Come.
DOCTOR (OOV.): Come along, man. Come along.
HARRY: This any good?
DOCTOR: We've done it, Harry. We've done it.
BENTON: Sir.
BRIGADIER: No one is to open fire. She may find a chance to get clear.
ROBOT: Stay here.
BENTON: It's going to att*ck, sir. Should we pull back?
BRIGADIER: Of course, the very thing. I think just for once, we're not going to need the Doctor.
BRIGADIER: Follow me and hold your fire till ordered.
ROBOT (To SARAH.): You will be safe. See how I deal with our enemies.
BRIGADIER: She's out of the line of fire. Launch your grenades.
BENTON: Smith, Hampton, get down here quickly with the launcher.
BENTON (OOV.): Fire!
BRIGADIER: Right, pull back!
HARRY: Curiouser and curiouser.
DOCTOR: Said Alice.
HARRY: Exactly.
DOCTOR: I see our little problem seems to have grown. Where's Sarah?
BENTON: She's safe enough, Doc.
BRIGADIER: I gave it a blast with the disintegrator g*n.
BENTON: It left her up on the roof.
DOCTOR: Really, Brigadier, you should be more careful with your little toys. You've given it just the infusion of energy it needed.
BRIGADIER: Well, I've sent for the a*tillery, and the RAF are on their way.
DOCTOR (OOV.): I hope that won't be necessary.
BRIGADIER: What on earth is that?
DOCTOR: Another piece of brilliance from the late Professor Kettlewell, and one that will solve our problem, I hope. Drive on, Harry.
HARRY: Right, Doctor.
DOCTOR: Wish me luck, Brigadier.
BRIGADIER: Now, just a moment, Doctor!
SARAH (OOV.): Hey! Hey, get me down!
BRIGADIER: Don't just stand there, Mr. Benton. Go and help Miss Smith.
BENTON: Right, sir.
BRIGADIER: What was that stuff?
DOCTOR: Some of Kettlewell's metal virus in an active solution.
BRIGADIER (OOV.): Will it work now the thing's that size?
DOCTOR: Oh, even faster I hope. Look. It's thrown the growth mechanism into reverse.
HARRY: Oh, well done, Doctor.
DOCTOR: Thank you, Harry.
BRIGADIER: I'll have it taken away. Broken-up, just in case.
DOCTOR: No. No, Brigadier, that won't be necessary. Look.
DOCTOR: Sarah. Sarah? Would you like a Jelly Baby? I had to do it, you know.
SARAH: Yes, yes, I know. It was insane and it did terrible things, but at first, it was so human.
DOCTOR: It was a wonderful creature capable of great good. And great evil. Yes, I think you could say it was human. You know, what you need is a change. How about a little trip in a TARDIS? I'm just off.
SARAH: Wait, you can't just go.
DOCTOR: Why not? It's a free cosmos.
SARAH: The Brigadier...
DOCTOR: The Brigadier wants me to address the Cabinet, have lunch at Downing Street, dinner at the Palace, and write 17 reports in triplicate. Well, I won't do it. I won't, I won't, I won't! Why should I?
SARAH: Doctor, you're being childish.
DOCTOR: Well, of course I am. There's no point in being grown-up if you can't be childish sometimes. Are you coming?
HARRY: Hello. Well, what are you two up to now, eh?
DOCTOR: We're just going on a little trip. Would you like a Jelly Baby?
HARRY: Little trip? What, in that old police box?
DOCTOR: Yes, as a matter of fact, in that old police box.
HARRY: Come along now, Doctor. We're both reasonable men. We both know that police boxes don't go careering around all over the place.
DOCTOR: Do we?
HARRY: Of course. The whole idea's absurd.
DOCTOR: Is it? Hmm. You wouldn't like to step inside a moment? Just to demonstrate that it is all an illusion.
HARRY: If you think it will do any good.
DOCTOR: Yes, it'll make me feel a lot better.
SARAH: Doctor!
DOCTOR: In you go.
HARRY: Right-o.
HARRY (OOV.): Oh, I say!
BRIGADIER: Doctor, about that dinner at the Palace, Her Majesty... Yes. Well, I'll tell them you'll be a little late.
