"(DOCTOR WHO THEME)" "(WHIRRING)" "Doctor, look!" "What is it?" "One of the creatures that have been destroying the ships." "You told me it was enemy agents." "Why didn't you tell me the truth?" "If I had, would you have believed me?" "There's only one thing for it." "We'll have to go through the minefield." "We'll get blown up." "No." "Don't worry." "My sonic screwdriver, it converts into rather a good mine detector." "(BEEPING)" "(BEEPING LOUDLY)" "Look out." "Look, there's one over there." "Now, you'll have to move round to the right." "Now follow me." "Okay." "Stupid beast." "Why doesn't it attack them?" "(WHIRRING LOUDLY)" "Doctor, it's following us." "Doctor!" "Relax, Jo, relax." "(SHRIEKING)" "Right, follow me." "Anything from the sub yet?" "It's no good, sir." "There's nothing." "They had instructions to surface over an hour ago." "Maybe they've found something, sir." "Perhaps they're still investigating." "If they haven't surfaced by now, then something must be stopping them." "All right, submiss procedure." "Alert submarine command." "We'll set up a full-scale search right away." "Sir." "MAN ON INTERCOM:" "Submarine indicator buoys still won't release, sir." "All right, Summers." "Radio Captain Hart the moment you surface." "Tell him we're immobilised on the seabed by some unknown force and intruders have broken through the hull." "Aye, aye, sir." "You've checked your RT?" "Yes, sir." "All right, carry on." "Good luck." "Something's happening to this door, sir." "It's getting hot." "Right, small arms, Number One." "Aye, sir." "Forward hatch is jammed, sir." "All right, Summers." "Johnson, here." "Petty Officer, here." "Right, take cover." "The door's going." "All right, Number One." "Hold your fire until we see who they are." "I just can't take it in." "It's all too much for me." "Trenchard, you really must be more calm." "Believe me, it's very simple." "Simple?" "You've misled me all along." "You said it was spies, saboteurs." "You said we'd catch them." "Look, if I had talked to you about sea monsters, would you have believed me?" "I've risked everything to help you and you've lied to me." "I had to lie." "Now, sit down, Trenchard." "Sit down and listen to me." "I don't know how you can be so calm." "Now, listen, that creature that you saw is one of a race of intelligent reptiles that has a deadly hatred of mankind." "Now, somehow they've established themselves in the sea, but now they intend to emerge and conquer the Earth." "What?" "We..." "We must warn the authorities at once!" "No, no, no." "Premature action would ruin everything." "What else can we do?" "Wait until this device of mine is perfected and then tell the authorities." "Hold still." "Hold still." "(GUARDS SHOUTING)" "We've got to get back to Captain Hart." "Come on." "They're not in the beach sector." "We've completely lost track of them." "Trenchard, if they reach the naval base..." "Exactly." "They'll tell Hart everything." "Mind you, there's a good chance that he won't believe them, of course." "But suppose he does?" "Suppose he turns up here again?" "Refuse to admit him." "Don't be ridiculous." "Trenchard, you are running a top security establishment here." "Your only responsibility is to the government." "Oh, what about the Doctor?" "He'll report to UNIT." "They can go to the government." "Now look, you must trust me a little longer." "I assure you all your troubles will soon be over." "MAN ON INTERCOM:" "Aft end dry of water, sir." "Why there?" "Ask Green Gilbert." "All right, old man." "Get you there in no time." "Er, sir, shall we take a look at the pressure gauge, sir?" "If you'll excuse me one moment?" "Sir, shouldn't we try and jump them?" "No." "You mean we're going to do nothing at all?" "Sooner or later, these things are gonna return to their base." "I want to know where that is." "Starboard 20, Number One." "I'm sorry if I seem to be repeating myself, Doctor, but I don't believe a word of it." "Well, I can assure you we didn't walk ten miles across open countryside just to tell you fairy stories." "Monsters coming out of the sea." "But it's different this time." "Everybody saw it, even Trenchard and the guards." "And you think Trenchard will confirm your story?" "I doubt it." "The Master's got some sort of hold over him." "The Doctor's seen these creatures before." "Oh, I'm quite sure he has, Miss Grant." "In some caves in Derbyshire." "You see, they want to take over the Earth." "Really, Miss Grant, if you think for one moment..." "We'll re-take it if you like." "What they're going to do is..." "All right, Jo, all right." "Let me deal with the explanations." "Look, it's like this..." "Only cheese, I'm afraid." "The best the steward could do." "Oh, that's super." "Thanks very much." "For heaven's sakes, Jo." "What do you think this is, a picnic?" "All right, well, let's forget about the sea devils." "What about Trenchard trying to take us prisoners, then?" "Well, I only have your word for that, haven't I?" "All right." "What about the theft of your electronic spares?" "Surely you'll agree that happened?" "Since I was here at the time, yes." "The Master stole those parts to make his calling device and..." "His what?" "Well, he's developed some way of communicating with them." "Probably a ultra-high frequency sonic beam." "These are rather good, want one?" "No, thank you." "Sandwich?" "Thank you." "Doctor!" "Oh, I'm so sorry." "(PHONE RINGING)" "Captain Hart's office?" "Oh, I see." "Yes, yes." "I'll tell him." "They've had to abandon the search, sir." "They'll start again at first light." "Very well." "I'll get you some more sandwiches." "JO:" "Thanks very much." "How overdue is the submarine?" "Four hours." "It should never have been sent, you know." "They were bound to presume it was hostile." "Kindly leave the naval side of this operation to me, Doctor." "Captain Hart, you are dealing with a situation completely outside of your own experience." "And if you won't let me help you..." "All right then, Doctor." "What do you want me to do?" "Well, the key to this whole situation is at the castle." "Sir, I think we've got something." "Where?" "There, sir." "Contact bearing two-seven-zero." "Range, 20,000 yards." "Heading zero-four-seven." "The submarine?" "Could be." "I think it must be, sir." "You see where the thing's heading?" "That beach by the castle." "Perhaps you'll believe me now." "(WHIRRING)" "(BUZZING)" "(WHIRRING)" "That thing working all right?" "It still needs a few minor adjustments, that's all." "Look, I've been giving some thought to all this." "It's going to be an enormous job coping with these creatures." "We must give the authorities all the notice we can." "(BUZZING)" "What was that?" "Just random feedback." "It's nothing important." "Sounded like some sort of message." "Look, Trenchard." "I am trying to carry out a very difficult and complex task here, and I can't work if I'm being continually interrupted." "I'm terribly sorry, old chap." "I'll leave you to it." "Thank you." "Yes." "(BUZZING)" "(WHIRRING)" "I tell you I must speak to the Minister." "It's most important." "Hmm?" "Well, when do you expect him back?" "No." "I can't tell you what's wrong." "The security of the nation is at risk." "Oh, very well." "I'll hold on, but please hurry!" "No." "It can't wait till the morning." "Oh, you'll have to interrupt his meeting." "This is a matter of national urgency." "Oh, very well, as soon as he's free, then." "But if there's any unnecessary delay, believe me, you'll answer for it." "Guard?" "(ALARM SOUNDING)" "What's happening, man?" "They're all over the place, sir." "They killed most of the lads." "Who's attacking us?" "Lizards, sir." "Like that thing we saw on the beach." "Come on, sir." "They were after me." "Pull yourself together, man." "Have you sent for help?" "But it's no good, sir!" "There's a direct line to Whitehall in my office." "Use that." "Why can't you, sir?" "I shall attend to the security of my prisoner." "Go on, man." "Move." "(ALARM STOPS)" "No, it's no good, sir." "Nothing." "Well, if that thing was the submarine, why don't they answer your signals?" "Perhaps they can't." "Tell the search coordinator to check that area immediately." "It'll be light soon." "Sir, contact fading." "What?" "Captain Hart, we've got to find out what's happening at that castle." "Contact lost." "I want an armed party and two Land Rovers at the main gate in four minutes flat." "Doctor?" "Come on." "Follow in." "Doctor!" "I don't understand why." "The Master had no further use for him, that's why." "But why did he help the Master in the first place?" "What would you say was Trenchard's strongest characteristic?" "Oh, I don't know." "Patriotism, I suppose." "Exactly." "And the Master used that patriotism as a weapon." "I've bought you some kye." "Roger, search force." "Over and out." "Did you get through to Captain Hart?" "I telephoned the castle, but they've already left." "Well, they're definitely getting an echo and the object's moving." "HART:" "What is it, Bowman?" "Have they re-established contact?" "It's a message from one of the search vessels, sir." "They are getting an echo." "The submarine?" "Yes, it's moving towards the fort now." "Moving at about 30 knots." "Depth?" "Steady at one-five-zero feet." "The fort." "Look, Captain Hart, can you lay on a diving vessel?" "Yes." "The Reclaim's standing by on the search, but why?" "I want to inspect the seabed at the base of that fort." "All pre-dive checks completed?" "Yes, sir." "Doctor, are you quite sure you want to go through with this?" "Yes, positive." "Ready to lower the observation chamber?" "Yes, sir." "The crew is standing by." "We'll send a man armed with him." "Good." "If you don't mind, I'd rather go down on my own." "Well, I presume you're a trained diver in addition to your other accomplishments then, Doctor?" "Naturally." "What's more, I know these creatures." "I've encountered them before, so I know what I'm looking for." "All right, carry on." "Aye, aye, sir." "Doctor?" "What is it, Jo?" "Is it really necessary for you to go down?" "How else am I going to make contact?" "Doctor?" "Well, good luck, Doctor." "Thank you, Captain Hart." "Everything okay, sir?" "Yes, thank you, Chief." "Very good." "Test the links." "(OFFICER SHOUTING ORDERS)" "(OFFICER SHOUTING ORDERS)" "Pull up the links." "Carry on lowering." "SAILOR:" "Twelve feet." "OFFICER:" "Carry on lowering." "Let me speak to him." "How's it going, Doctor?" "Splendid, thank you." "A most interesting trip." "You'll reach seabed in a few minutes." "Tell us immediately if anything goes wrong." "Don't worry." "I'll be all right." "You have reached the seabed." "Right." "Are you all right, Doctor?" "Yes, I'm fine, thank you." "Hang on a minute!" "Are you all right, Doctor?" "Shall we bring you up?" "Definitely not!" "I think I've just... (STATIC)" "Bring him up!" "Start winches!" "Hoist SCC!" "(SAILOR SHOUTING)"
