WEBVTT 01:00.000 --> 01:23.360 And there's no news from cave mouth to we've lost contact with cave mouth to sir 01:23.360 --> 01:30.920 well I want to report small sectors as they come in and get me captain Hawkins sir I've 01:30.920 --> 01:35.320 checked on the ambulance man in the sickbay the discoloration of the skin is fading rapidly 01:35.320 --> 01:41.520 so the doctors antidote seems totally effective so far yes she'd get a move on with that formula 01:41.520 --> 02:00.280 quickly there may be others 02:11.520 --> 02:31.320 I know I'm terribly sorry look what's happening about my call to the Ministry of Defense I'm 02:31.320 --> 02:35.600 sure the doctor won't be much longer well look hurry it up man this is top priority I do realize 02:35.600 --> 02:44.160 all right trouble dr. Meredith is getting very impatient I can't say I blame him give the doctor 02:44.160 --> 03:06.760 a couple more moments I mean he may have run into some kind of problem 03:06.760 --> 03:17.520 it's all right major Walton pull back from gallery four and try to hold them at cave mouth three 03:17.520 --> 03:28.800 over and out the Ministry of Defense miss Shaw I must have that formula all right let's 03:28.800 --> 03:36.480 do it here sir you've got my message with respect sir I don't think you appreciate the 03:36.480 --> 03:42.080 gravity of the situation but there's no time to refer it to the Defense Committee 03:42.080 --> 04:08.360 but where is he I've told you I've no idea read the formula to dr. Crawford he's been hanging on 04:08.360 --> 04:14.440 long enough don't you understand I don't know which is the formula hello dr. Crawford look I'm 04:14.440 --> 04:20.120 afraid I'll have to ring you back there's been yet another delay yes yes yes as soon as I can 04:20.120 --> 04:26.360 Brigadier there was some glass in the lab I don't know sir there's been some kind of a raid 04:26.360 --> 04:32.640 private Upton's dead in the caves no sir here just down the corridor and there's a kind of 04:32.640 --> 04:39.320 scorch mark on the wall stay here miss Hawthorne stay here yes of course 04:39.320 --> 05:08.560 get me dr. Crawford please how many humans have survived the epidemic they will all survive 05:08.560 --> 05:15.520 that is impossible you have discovered a cure yes and soon all the humans will be immune to 05:15.520 --> 05:22.000 your epidemic your plan has failed as your leader wanted it to fail our leader is dead I killed him 05:22.000 --> 05:32.240 I am the leader now thank you dr. Crawford the Silurians have broken in well what about the 05:32.240 --> 05:38.200 doctor well I imagine they've taken him to their base Captain Hawkins send every man we've got into 05:38.200 --> 05:42.080 the caves and I want all civilian personnel evacuated from here immediately sir and organize 05:42.080 --> 05:45.880 a thorough search of that laboratory I'll see to it myself sir you two come with me I give them the 05:45.880 --> 05:49.480 formula to dr. Crawford they're going to make their own tests and then going to mass production 05:49.480 --> 05:54.960 with the antidote well done miss Shaw what are you going to do about the doctor what can I do 05:54.960 --> 06:01.680 try to rescue him you'll have to attack their base at the moment they seem to be attacking us 06:01.680 --> 06:11.640 since the epidemic has failed we must use other means we intend to make this planet uninhabitable 06:11.640 --> 06:18.240 for human beings you can't do that you can't exterminate a whole species is this person ready 06:18.240 --> 06:24.680 for activation all we need now is the power we shall continue to use the electricity of the 06:24.680 --> 06:30.400 humans won't be able to do that thanks to you the humans are no longer making power 06:30.400 --> 06:38.280 that generator has been switched off then you will help us we shall force you to reactivate it 06:38.280 --> 06:46.360 we shall take the center hello hello hello switchboard what's the matter with this thing 06:46.360 --> 07:03.200 the devil we seem to have switched to an emergency lighting system instead this one's dead too and 07:03.200 --> 07:07.400 I've just sent the last of my men into those caves because of the attack I sent every man 07:07.400 --> 07:11.320 I've got down to the caves now the Silerians are cutting our communications what about your 07:11.320 --> 07:17.280 pocket radio now useless at this depth they could break in once to get the doctor they 07:17.280 --> 07:22.840 could break in again exactly only this time it'll be in force 07:22.840 --> 07:43.720 is the machinery prepared I could do nothing without power from the humans generator it 07:43.720 --> 07:49.600 has ceased to function we shall force them to reactivate it when your instruments register 07:49.600 --> 07:56.240 the power you will revive all our people now I shall take the one called the doctor to the 07:56.240 --> 08:07.920 research center I'll go to the ministry myself we need a division down here now see we get it 08:07.920 --> 08:18.680 what's matter with this thing the telephone stopped working now the lift as well Brigadier 08:18.680 --> 08:47.040 look doctor do as he says Brigadier or they'll kill us all we do not need these humans miss 08:47.040 --> 08:52.800 always a scientist if I'm to do what you want I shall need her help the other one is a soldier 08:52.800 --> 09:05.520 he is dangerous kill it you'll have to kill me too you will take us to the nuclear generator 09:05.520 --> 09:30.680 oh we will kill you all I said there was to be no more killing I stay where you are this 09:30.680 --> 09:37.160 center is now in the hands of the Silurians they need the use of the generator now if you follow 09:37.160 --> 09:42.160 carefully the instructions I shall give you your lives may be spared remove the bodies 09:42.160 --> 09:47.320 doctor what do you think you're doing trying to save your lives I keep on the way and keep 09:47.320 --> 10:05.440 what you will now connect this device to the nuclear generator the power source is over here 10:05.440 --> 10:10.280 what is the purpose of this machine that is no concern of yours if I'm to help you I must know 10:10.280 --> 10:18.440 this is the molecular disperser it will convert the energy of the nuclear reactor into microwaves 10:18.440 --> 10:25.440 what purpose the microwaves will disperse the molecules of the filter built which is 10:25.440 --> 10:31.000 enveloped this planet since our time but if this process gets out of hand it will destroy 10:31.000 --> 10:40.720 all life on the planet we can control the process commits work what are they gonna do 10:40.720 --> 10:48.200 destroy the Van Allen belt what the Van Allen belt it surrounds the planet and filters out 10:48.200 --> 10:54.720 some of the Sun's radiation what happens when it's gone it's so hot we will all die of sunburn 10:54.720 --> 11:02.360 on a cloudy day what good will that do them the reptile cold blooded they'll thrive in heat we 11:02.360 --> 11:05.240 shall die it'll be the end of the human race 11:05.240 --> 11:20.360 the generator of the humans is producing power commits the revival process 11:35.240 --> 11:48.600 you will now provide power to operate the de-hybernation machinery and activate the 11:48.600 --> 11:54.720 disperser yes well we'll need to stoke up the reactor miss Shaw I'll need your help 11:54.720 --> 12:03.200 you mustn't tell him the doctor knows what he's doing trust him miss Shaw I want you to feed 12:03.200 --> 12:11.040 uranium into the reactor all right when I tell you lower all the rods in at once doctor Liz I know 12:11.040 --> 12:21.360 what I'm doing please do as I say all technicians your usual sectors please your usual sectors 12:21.360 --> 12:38.800 please all right Liz yes lower in number one rod number one rod check lower in number two rod 12:38.800 --> 12:52.320 number two rod check the sector one increase your power level lower in number three rod 12:52.320 --> 13:02.800 you should be getting enough power now to get your disperser unit into operation 13:10.000 --> 13:11.960 continue to increase the power 13:11.960 --> 13:18.580 No 13:41.960 --> 13:47.960 The reactor is now permanently overloaded. 13:47.960 --> 13:53.960 There's going to be a massive explosion and a colossal radiation leakage. 13:53.960 --> 13:55.960 The whole area will become deadly. 13:55.960 --> 13:56.960 For how long? 13:56.960 --> 13:58.960 For 45, possibly more. 13:58.960 --> 14:01.960 This means nothing to us. 14:01.960 --> 14:07.960 We shall return to our base, waiting hibernation until the radiation has faded. 14:07.960 --> 14:10.960 Kill these humans! No! 14:10.960 --> 14:14.960 They will all stay here to die from the radiation. 14:35.960 --> 14:37.960 Well done, Dr. Fowler. 14:37.960 --> 14:39.960 Well done, Regear. 14:41.960 --> 14:43.960 Perland, you better close down the reactor. 14:43.960 --> 14:45.960 I can't. 14:45.960 --> 14:47.960 You were swallowing nothing. 14:47.960 --> 14:49.960 Well, I exaggerated a bit. 14:49.960 --> 14:53.960 I had to push the reactor past the critical stage or they'd never have believed me. 14:53.960 --> 14:55.960 You better get out of here at once. 14:55.960 --> 14:56.960 We can't. 14:56.960 --> 14:57.960 Why not? 14:57.960 --> 15:14.960 They've jammed the lift. There's no way out. 15:19.960 --> 15:22.960 The re-hibernation mechanism is defective. 15:22.960 --> 15:24.960 One of us must remain. 15:24.960 --> 15:27.960 I am the leader. The responsibility is mine. 15:27.960 --> 15:30.960 The one who remains here will die. 15:30.960 --> 15:34.960 Is sufficient power stored in the hibernation unit? 15:34.960 --> 15:40.960 Yes. I have set the controls to revive us in 50 years from now. 15:40.960 --> 15:44.960 When our people revive, you will be the leader. 15:44.960 --> 15:57.960 See that the apes are destroyed. 15:57.960 --> 15:58.960 Any good now? 15:58.960 --> 16:00.960 No, it's still not working. 16:00.960 --> 16:23.960 Give me time, Liz. Give me time. 16:23.960 --> 16:26.960 Here you are. Try that now. 16:26.960 --> 16:36.960 The water is still rising. 16:36.960 --> 16:39.960 Yes, I know. I'll try fusing the control of the neutron flow. 16:39.960 --> 16:55.960 Now stand well back and cover your eyes. 16:55.960 --> 16:57.960 Well, that seems to have done it. 17:26.960 --> 17:30.960 You are still alive. You tricked us. 17:30.960 --> 17:33.960 I managed to close down the reactor. 17:33.960 --> 17:36.960 Then the others must be revived at once. 17:36.960 --> 17:54.960 At first, I shall kill you. 17:54.960 --> 17:56.960 Well, that's done, Brigadier. 17:56.960 --> 17:58.960 Now then. 17:58.960 --> 18:00.960 And just what do you think you're doing down here? 18:00.960 --> 18:03.960 I'm trying to find out how this hibernation unit works. 18:03.960 --> 18:05.960 I must know if we're going to revive them again. 18:05.960 --> 18:07.960 Revive them? 18:07.960 --> 18:09.960 It's not all at once, you understand. 18:09.960 --> 18:12.960 But one at a time so that we can reason with them. 18:12.960 --> 18:15.960 There's a wealth of scientific knowledge down here, Brigadier. 18:15.960 --> 18:23.960 And I can't wait to get started on it. 18:23.960 --> 18:25.960 I think it's going to be working quite smoothly. 18:25.960 --> 18:27.960 I don't think there'll be any more trouble. 18:27.960 --> 18:28.960 Splendid. 18:28.960 --> 18:32.960 Now, don't forget, Brigadier, nobody is to go into that Silurian base. 18:32.960 --> 18:33.960 Yes, Doctor. 18:33.960 --> 18:36.960 And Miss Shawna will be back as soon as possible with some testing equipment 18:36.960 --> 18:38.960 and probably some other scientists. 18:38.960 --> 18:40.960 Good, good. Well, have a good journey. 18:40.960 --> 18:42.960 Yes. 18:42.960 --> 18:46.960 But don't forget, Brigadier, nobody is to go into that base. 18:46.960 --> 18:48.960 All right? 18:48.960 --> 18:50.960 See you tomorrow. 18:50.960 --> 18:51.960 Goodbye. 18:50.960 --> 18:52.960 Goodbye, Miss Shaw. 18:52.960 --> 18:54.960 Goodbye. 18:57.960 --> 18:59.960 Corporal Nutting. 18:59.960 --> 19:00.960 Sir. 19:00.960 --> 19:02.960 Everything's set up. 19:02.960 --> 19:03.960 Yes, sir. 19:03.960 --> 19:07.960 Give them time to get clear and then set off those explosive charges. 19:07.960 --> 19:22.960 And keep that Silurian base sealed permanently. 19:37.960 --> 19:39.960 Shall I walk back and get some help? 19:39.960 --> 19:40.960 No, no. 19:40.960 --> 19:42.960 This is a minor technical fault. 19:42.960 --> 20:08.960 We'll soon put that right. 20:08.960 --> 20:36.960 Okay. 20:36.960 --> 20:39.960 There you are.
