Yes, Doctor. I see you take my meaning. Guts, take him to the preparation room. Leave it alone. It didn't take them long to find it. I hope they don't do any damage. Well, there's nothing they can do, unless they get inside. Are they bringing it in here? No. Doesn't look like it. Take a look for yourself, Vicki. Oh, what do we do now? Find the Doctor, I suppose. I'm afraid I'm no great expert when it comes to changing the future. I think one of us should keep watch on the TARDIS. If we want to leave in here in a hurry, we don't want to have to waste time looking for it. But we know where it's going, Vicki. We've already seen it. Well, if it gets there, we needn't bother. We want to change what's going to happen in the future. Oh, this is a bad idea. I'm afraid we can't. I'm afraid we can't. I'm afraid we can't. I'm afraid we can't. I'm afraid we can't. I'm afraid we can't. I'm afraid we can't. saying this whole thing is a nightmare. Why don't we do something? Choice is only possible when you know all the facts. Don't you realize we know nothing about this place? Shh! Listen. Keep clear! And move! Move! Is there no way in? No, Commander. That's all I need. You know what Lobus will say about that, soldier. He will blame me. Everything that goes wrong on this wretched planet is my fault. Think yourselves lucky that you have me between you and our illustrious governor. A scapegoat, and for what? For this rank and a meager pittance of extra pay. Oh, what's the use? Strange-looking craft. Must be very cramped and uncomfortable for four travelers like us. Must be very cramped and uncomfortable for four travelers inside at one time. Yes. The store is locked. We could not gain entry, sir. Didn't they leave you the key? Fawcett, open your phone! Why was not the cutting equipment brought to me? I asked you to bring it several times, didn't I, soldier? Now don't you give me any of your feeble excuses. I will deal with you later. Get it! Incompetent fools. Have any of the aliens been caught, sir? One has. Three are still at large. Do you hear that? Yes. They could be in a thousand places. Then I expect a thousand places to be searched. When this is over, discipline will be tightened. The army here has gone soft. I'm supposed to have at my command trained soldiers, not a feeble bunch of half-witted amateurs. They've stopped talking. Maybe they've gone. Stairs you're up. You. You with a gun. Bring it to me. Um, careful. Don't move! Don't you fire that thing! Well, wouldn't that change the shape of things to come? Well, it would for you. You'd be dead. They can't kill us. We're going to end up in those cases. Not necessarily. Oh, you can change the future so that we don't end up in those cases. But if we're all dead, what's the point? That means we can't fight against anybody. We don't know what we're doing. We've just lost the doctor. Has that already changed the future? We don't know, Vicki. Maybe that's the way it happened. We've no reason to suppose that we all ended up in the cases at exactly the same time. So we could be doing exactly what we're supposed to do. I've had enough of this. Now listen, we're going to deal with him. And then we're going after the doctor, whether we're supposed to or not. That's enough talking. Come on, move out. Slowly. Vicki, don't worry. I'm going to try something. I said move out. Yes, we heard you the first time, but we don't feel like moving, do we? No, definitely not. Ian, don't go too far. Now what were your orders? To capture us? To bring us in? Yes, get back. Back. There was nothing about killing us, was there? Well, was there? Answer me. No, no, no, there wasn't. Think what your superiors are going to say. They're going to ask, did you bring in the aliens? No, you're going to reply, I went out and shot them all. Now run! Both of you! Ian, stop it! Now move! Open those doors! Open them! Vicki! Get out of those rooms! Guards, with me! Take them to my office. Wait for me there. Guards! Guards! Vicki! Why don't you take that friend? Why don't you take that friend? Thanks, lad. Thanks, lad. Let me go! Let go! Quiet, they're here. Look, you've got to trust us. Why should I? We hate the Morrocks. We want to see them dead. You can see we're nothing like them. Who are you? We'll explain everything later. First of all, we must find your companions. It was you who took the doctor. Like you took me, the old man who was with us. Yes, but... We did, but he fooled us. Then the Morrocks caught him. Oh, we didn't hand him over to them, if that's what you're thinking. Now, where are the others? I think they caught Ian. The man? What of the woman? We ran so quickly we went in opposite directions. I couldn't turn back when I realized, because the guards were already behind me. She must be making for the storerooms. We'll have to wait at the headquarters. Darko? Go and see if you can find her and bring her there. What's her name? Barbara. Go quickly. You fools! You let them escape? Yes, sir. There are other ways of getting them out. Withdraw our men from this building. Have all exits guarded and have the rest search the area for the one these fools allowed to escape. You remain here. Who's there? No, no, no. Don't kill me. Don't. It depends on you. I want the answers to some questions. If I can help you, I will. I promise. I had a friend of mine. An old man. He's been captured. Now what's happened to him? I don't know. I don't know. Is he dead? No, no. Where is he? They took him to the preparation room, but it's nothing to do with me. I'm just a simple soldier. What happens there? I said, what happens there? He'll be got ready for the museum. But you can't help him once the process starts. What process? It's a kind of embalming. How long does it take? Well, several hours, but... Take me there. Well, you'll be killed. Take me. We'll both be killed. A directive from Moorock. They think we made a mistake in allowing the Zeron youth to live. They're almost men and dangerous. These aliens, they've made fools of us. Burning 6-2, the ventilation is standard? Yes, sir. Good. It won't take the guards long to withdraw. In one hour, the air is to be replaced with Zafra gas. Is that clear? Perfectly. And see that my order is carried out. Zafra gas. It is very effective. If the two women do not leave the building and surrender to the guards, the gas will eventually paralyze them. Barbara, are you in here? Who are you? How do you know my name? There's no guard here. Hurry! Can't we wait for Barbara? Oh, no, it's too dangerous. Darko will find her and bring her to the hideout. Come on, quickly. Tor and Cetra have taken Vicky to our headquarters. You must believe me. We are your friends. Why should you be? We're Zerons. This is our planet. And the others? The ones in uniform? Morrocks. They changed our planet into a museum. A record of their wars. But soon we shall rise against them and drive them from Xeros. Morrocks? Where did they come from? Their planet's three light years away. They invaded us without warning. Xeros was a place of peace. And knowledge and the wisdom of our elders made us free from want. Why didn't you fight back? Their weapons were far superior to ours. We had planned for peace and they for war. Now I want you to come with me. Can you get us out of here? There are many guards, but I'll find a way. Come on. Look! They've set the museum on fire. That isn't smoking. It's gas. Put something over your mouth. So then what happened after the Morrocks had captured the planet? They destroyed everything. Even our people. Only the children were spared to work. How horrible. We are a slave race. When we grow older, we are taken to other planets. Ceta, Darkon, myself are due to go. But that is why we hide here and plan. But although we sworn to drive the Morrocks from Xeros, it will not be easy. The life they impose on us makes organization difficult. But there don't seem to be many Morrocks. Surely you must outnumber them. It is unpleasant to admit, but our opposition is weak and unarmed. A very small army can easily keep control. But you're supposed to be planning a revolution. Why did you and your friends come to Xeros? We... It was an accident. Of course. No one would come to Xeros from choice. The Morrocks reputation is universal. It's late. I'm sure Darkon and your friend Barbara have been captured. Well, I need time to dodge the guards. Well, this time we'll be fooling ourselves to believe otherwise. Well, you can't just accept it. We've got to help them. Of course, sitting here planning and dreaming of a revolution isn't going to win your planet back. We do all we can. By making a nuisance of yourselves, that's all it is. But what can we do without weapons? Nothing. We must get some. Now who's dreaming? The Morrocks are armed. So we take them from the Morrocks. Why not? That is revolution. Oh, Vicky, we have tried. Occasionally we have overpowered a guard and taken his ray gun. But what can one gun do against even a small army? And when we do that, they take hostages until the gun is returned. Where are the guns kept? At the armory. If you had guns, lots of them, could you organize your friends, distribute the arms and really wage a war? Of course. That is where we are strong, in our planning. But the armory is out of our reach. Don't you know where it is? Oh, we know, but its key is something that we could never attain. I don't understand. The armaments are kept behind locked doors, an impregnable safe. What kind of lock does it have? An electronic brain, programmed to ask questions. The answers given open the door, but they only open to the truth. A sort of lie detector. If I could see it, maybe I could... Well, I'd just like to see it. We could take it. But why are you so interested, Miss Vicky? Why do you want this revolution so much? I have as many reasons as you. Perhaps more, for wanting to see the future changed. Perhaps I'll explain later, but I think we should go now. What's wrong? This is the building. Well, take me in. It would be better to wait. It's a busy time of day. Later on, there won't be so many guards on duty. You'll stand a better chance. There's someone coming. Find out what happened to the others. And remember, I'm here. Soldier! What are you doing here, soldier? Why have you left your post? The governor sent for me. I am to report to him. You didn't leave it unguarded, did you? The replacement hadn't arrived. What? The governor's orders. He said immediately. Then why are you waiting? I will attend to your replacement. Sir. What is it now, soldier? Have the aliens been recaptured? Not yet. But the safra gas will soon drive them from their hiding place. You did well. Take your advice and wait a while. Over there. Well? This is the armory, Vicki. These must be the light beams. Yes. Can you do anything? Do you know how it works? It must work to a standard pattern. Break the light beam. The questions will start. Yes, I know. Do you understand that all questions are to be fully answered? Yes. What is your rank? I have no rank. You see, Vicki, not only does the reply have to be true, it has to be the correct answer as well. Yes. Sita, break the light beam again, but this time don't answer. Just let the questions run right through. Do you understand that all questions are to be fully answered? Yes. What is your rank? I have no rank. You see, Vicki, not only does the reply have to be true, it has to be the correct answer as well. Yes. Do you understand that all questions are to be fully answered? Yes. What is your rank? I have no rank. You see, Vicki, not only does the reply have to be true, it has to be the correct answer as well. Yes. What is your name? I have no name. Do you have the governor's permission to approach? Yes. The withdrawal requisition numbers are fed in from headquarters. It has to tally with the number given. There's no chance, Vicki. Which arm are you attached to? Isn't there? I wouldn't give in as easily as that. What purpose are the arms needed? Look, now this is where the questions are recorded. Has the guard on duty examined your identification papers? Help me get the front door. What is the current password? Are the aliens still in the building? Yes, sir. We have seen no movement. Very well. Keep the men alerted. They'll soon be coming out. Yes. We're almost there, Doctor. Doctor, come on. Have you done it? I'm not sure. I think so. The door hasn't opened. I've got to answer the questions yet. Then you've failed. The lock reacts only to the truth. And it still does, Tor. You'll see. What is your name? Vicki. For what purpose are the arms needed? Revolution. Well done, Vicki. I fixed it so that I only had to answer the truth. I didn't have to get the correct reply. It's everything we need here and more we'll be able to arm everybody. Oh, good. Get as many as you can carry and give them to Shamford. Dispose of the rest of the men. I'll give mine to the Tom and Corrine and bring them back here for more. I wonder if this will keep us out of the cases. Come in. Well, at last. You aliens have caused me enough trouble. I shall see that you pay for it. You'll be a fool if you kill me. You will achieve nothing. Possibly, but it might be enjoyable. What do you want? Take me to the doctor. The old man you captured. And if I refuse? I don't think you'll be that stupid. You'll kill me anyway. You're wasting time. I'm not wasting time. I'm not wasting time. I'm not wasting time. I'm not wasting time. You'll kill me anyway. You're wasting time. Am I? It is too late for you to help him. He has already passed into the second stage of preparation. And what does that mean? He is beyond your help. Come on, take me to him. Move. Hurry. Hurrying won't help your friend the doctor. Is he in there? Yes. Open the door. Now get in, both of you. Doctor. Doctor.
