Is he in here? Yes. Open the door. Now get in, both of you. What have you done to him? I don't think you would appreciate the technical difficulties. Just tell me what you've done. He has completed the second stage of preparation. He's as good as dead. You want to save yourself, you better bring him back to life. Impossible. But your only hope is to try. No one has ever attempted to reverse the process. There's a first time for everything. Now get moving. And remember, I shall be watching you very carefully. So don't try any tricks. There are no tricks in science. Only facts. How long is this going to take? How can I say? This has never been done before. Perhaps he never will recover. It's nearly the lot. All right, move along, hurry up. Just a minute, Vicki. Right, now you know the main objective. The Moorlach barracks. Most of our forces are already on the way there. But we must surprise them. If they mobilize, we shall fail. Come on, take a rig up. Thor, will everybody be going to the barracks? We need every man and woman we can muster, Vicki. Why? Well, if it's all the same to you, I'm going back to the museum. The museum? Barbara may still be there. I've got to find her, Thor. And my other friends. Look, after we finish here, you can get... Now! It may be too late then. I won't let you go. I won't let you stop me. But if you're captured? The Moorlachs don't know of the revolt. I'm not likely to tell them. You won't have to. The gun will give us away. They'll check the armory. I'm still going. Look, Thor, I've got to find them and tell them what's going on. There's no knowing what they'll do otherwise. If I am captured... I'll just have to hope that you're successful and you find me in time. I know it sounds silly, but whatever I do may be wrong. I... I've got to find them. Vicki. Yes? Sita, go with Vicki to the museum. I'll join you later. Yes, but... Don't argue, Sita. Do what she tells you. Come on, Sita. Hold up. Leave that. Leave that. There's a relief guard for this entrance. There was no one here when we arrived, sir. You, take over the watch. Sir. Come with me. I'll get to the bottom of this. Doctor. Doctor, come on. Well, what's happening? His temperature is returning to normal. Good. Can't you speed things up a bit? After a temperature of several hundred degrees below freezing, it is a complicated process. You will have to be patient. Body temperature has now been reached. Well? Yes. He's getting warmer. Good. We shan't have long to wait. Ah. Get back. Ah. Ah. Oh, support me, dear boy. Support me over there. Sit me down. Ah. How are you feeling? I shall be all right in a minute. It's a bad attack of rheumatism. It always happens to me when I'm cold. You've been cold all right, doctor. I can tell you that. Yes, unfortunately, I am not used to being subjected to such low temperatures. I give you word, you Russian. Well, you better bring the circulation back. That's an order. It's all right, dear boy. It's not the circulation. Please. Yes, don't fuss. Don't do that. Now. My dear Glavnik. My dear Lobos, I don't think your soldiers have really got their heart in their job, have they? Thank you for getting me out of this little predicament. Although I would have been better pleased had you done it more voluntarily. Yes, his conscience did need reminding. Yes. I know. I know. What do you mean, you know? Surely you were... Dead? Not at all, my boy. Not at all. I was merely, let me say, frozen stiff. You mean you knew everything that was happening? Exactly. My brain was working with the speed of a mechanical computer. I was asking myself questions. And the answers were arriving with remarkable alacrity. Yes, yes. I must confess I didn't enjoy the refrigeration, hence this attack of rheumatism. But thanks to you, my dear boy, I'm now de-iced and I think I'm quite capable of facing up to the climate once more. I wouldn't be too sure of that, doctor. Of course, I have no proof. But your brain could very easily have been affected. The best thing for you, Governor Lobos, is to put you in there. Then you will have all the proof you needed. But you think yourself lucky. My conscience won't allow me to do that. It's a pity, isn't it? It's a pity! Well, doctor, I think the next thing to do is find Barbara and Vicki. I'm not so sure of that, my boy. Where did you say you left them? The museum. And the charts? Well, that was outside the museum building. I see, I see. What's the problem? Surely we've changed the future by now. Yes, and I'm not sure of that either, Chesterton, have we? Have we? Or are we doing what we're allegedly intended to do? Now, what do you think? Well, I got you out of that thing. Yes, that's true. That's true. But I'm sure the Governor here would be delighted if we were both put back in there. Am I correct, sir? Hmm? Yes, doctor, you are quite correct. And it would appear that I shall have my wish. There's only a few more feet, doctor. There'll be guards out there, Bob, waiting for us. You'll stand a better chance outside. Chance of what? I met this soldier on his way here, asked him what he was doing. He said reporting to you on your orders. I was a prisoner of one of the aliens, sir. He had a gun, which he took from you. Yes, sir. I passed it to the relief guard and then came back here to see what was happening. You did well, commander. Have this man placed under close arrest. Yes? Relief guard, exit 417. The aliens are just about to leave the museum. Good. Detain them there. I'll send extra men. Yes, sir. Well, it would appear that this little diversion will soon be over, commander. Strange, no reply from the barracks. Well, it seems that a faulty connection has given our friend here another chance. Go with the commander. When you've got them, bring the aliens to me. Yes, sir. I've just had a word about your friends. You'll all be together again soon. Perhaps for centuries. Halt! Halt! There you are. Over. Sorry, Barbara. It's all right. It wasn't your fault. No talking. Hands on your heads. Up, up! Soldier! Vicki! Barbara, are you all right? You look terrible. No, I'm fine. Where did you come from? And guns? Yes, the revolution's finally started. We broke into the armory. Thor's leading an attack on the Morroc barracks. Well, why aren't you there? We came for you. Is he still inside? Well, I don't see how he could be. I think he must have been captured by the guards. Taken to wherever the doctor is, I suppose. Barbara, we've got to find them. We've got a chance now. Why? What's happened? Everything's going to be all right. I know it is. When the revolution succeeds, Thor and the Xerons are going to destroy this museum and all the exhibits. Well, we can't be put in a museum that doesn't exist anymore, can we? Darkar and myself are going to try and see if we can find Thor. Are you coming? No, I don't think so, are we, Barbara? Well, we must find out where Ian and the doctor were taken. And if that means just wandering around the exhibition aimlessly, well, we may as well go with them. Thor, where will they be taken? In the governor's office, I expect. First of all, anyway. We don't want to go there, do we? Possibly not, but that's where you are going. Oh, Ceta. Where did you get this? I asked you a question. I... I can't remember. Soldier, have there been any Kreella actions against us? None recently. Have any arms fallen into Xeron hands? No, sir. Not that I know of. It seems as though our illustrious governor is going to have more than his usual batch of questions to ask. Move. It seems as though our illustrious governor is going to have more than his usual batch of questions to ask. Move. No answer. No. First the barracks, now the armory. No, the soldier will report as soon as he gets there. Yes, sir. You don't think... I don't think anything, Commander. All I know is that this gun came from the weapons store. What is going to happen to them? In due course, they will go into the museum as planned. Chesterton, Chesterton! Save your strength. It's going to take much more than that to get us out of this situation. Hello. Exhibits in a forgotten museum, eh? Is that how we're all going to end up? Not with this apparatus. Well, my boy, you'd hardly call me a pessimist, but I think it's most unlikely that that is the only contraption of its kind. Well, you can't blame Ian for letting off steam, Doctor. I wish I'd have thought of it. I'd have smashed the whole thing too. Yes, I think I would have done the same thing. But we must have changed the future. We just must have done. Must we, Vicki? Or were all the things that happened planned out for us? Hmm. Four separate journeys. Four choices. That led all the time closer to here. Maybe it would have changed things if I hadn't left that museum. Yes, and perhaps I shouldn't have got myself captured. Well, if you're all joining in, I suppose I... Oh, what's the use? It hasn't happened yet, you know. Yes, Vicki's quite right. Quite right. It's only a matter of time, isn't it, Doctor? Well, it's not necessarily, my boy. But Doctor, what can we do now? My dear Barbara, you must try and remember the short time we've been on this planet. We've met people, spoken to them, and who knows, we might have even influenced them. That's what I was trying to say, Doctor. Yes, I knew you were, child. Yes, I knew you were. You mean we don't necessarily have to change our own future. It could be changed for us. Quite so, yes. Quite so, my boy. Like the revolution. To headquarters, quickly! Look out! Tarko! Tarko! It's Thor! Thor! The barracks, did you... Destroyed. The Morrocks are on the run. And Vicki, do you know what happened? She found her friends. Then the Morrocks came. They took them? Yes. Well, where to, Tarko? Where did they take them? I'm not sure. The Governor's office, I think. Stay with him. The rest of you, come with me. Yes, Arling? Yes, sir. What's happening? The barracks have been attacked. The weapons have gone. What? Stay there. I'll send extra men. No, the barracks have been wiped out. The Zerons have gone... Argh! Hello. Hello, this is Governor Lobos. You still get away. I've got a ship standing by at the launch port. What about the aliens? All this trouble started when they arrived. Kill them. Lobos! Tark! Vicki! Oh, marvellous. Oh, thank you. The future doesn't look too bad after all, does it? Oh, that's just going to be... Oh, let's go. Well, it didn't take them long to dismantle the museum, did it? No. Well, it must be quite a feeling getting your own planet back. Ah, there you both are. Hmm? That's it. That's the little thing that's been giving us all this dimensional trouble. Hmm? Just that. You know, it's a funny thing how it happened. It got stuck. I don't know whether you've gone into a room and switched on the light and had to wait for a second or two before the thing lit itself up. Hmm? Yes, I have. I think most people have. Well, this is the same kind of problem, you see. We landed on a separate time track, wandered around a bit, and until this little thing clicked itself into place, we hadn't actually arrived. Ah. Well, thanks very much for explaining it. Not at all, my dear boy. Any time. Any time. Hmm. Yes, uh, well, uh, do you want it back? Ah, yes, uh, please, yes. I wonder if you'd mind taking it in for me inside the ship. Thank you. I just want to fetch Vicki. Yes. There, now, uh... But, Thor, surely it doesn't all have to be destroyed. Can't you use any of it? Oh, we only want on Zerus what belongs to Zerus, Vicki. The rest will be broken up. Yes, I think I can quite understand your sentiments, young man. But, you know, you mustn't, uh, lose sight of science altogether. You might need it. Oh, yes, Doctor. Doctor, what is that extraordinary thing you've got in the TARDIS? Ah, that, my boy, yes. Well, that I got from the Space Museum. This young man here, Thor, he very kindly gave it to me as a souvenir. A souvenir? Couldn't you get something a little smaller? My dear Chesterton, I don't think I have to ask your permission for what I take in my ship, and another thing. I will not have... Oh, no, Doctor, of course you don't. But, uh, what is it? It looks terribly interesting. Yes, well, as a matter of fact, my dear, it's what they call a time and space visualiser. You know, I couldn't believe my eyes when I saw it in the Space Museum. And I have an idea. I can get it working again. Yes, Doctor, but what exactly does it do? You will see, you will see. All in good time. Now then, have you said your goodbyes? Yes, sir. Thank you, Doctor. Your party made our revolution a success. Splendid, splendid. Well, now I think we must get moving. Goodbye, young man. Goodbye, Doctor. Goodbye, Tor. Come along, my child. Come along. Goodbye, Vicki. Goodbye, Tor. Our greatest enemies have left the planet Zeros. They are once again in time and space. They cannot escape. Our time machine will soon follow them. They will be exterminated. Exterminated. Exterminated. Exterminated. Exterminated. Exterminated. Exterminated. Exterminated.
