"Anything, Lieutenant?" "No, sir." "I've tried every major transmitting station on Deneva." "None of them have acknowledged my contact signal." "Try GSK-783, subspace frequency 3." "Sir, that's a call sign for a private transmitter." "I'm very well aware of that, Lieutenant." "Try it." "Yes, sir." "Evaluation, Mr. Spock." "As I speculated, Captain, the overall pattern of mass insanity destroying civilizations follows an almost straight line through this section of the galaxy." "Over here the Beta Portilin system -- the ancient civilizations." "Archaeologists have given us information indicating that they were the beginning." "200 years ago," "Lavinius 5 was swept by mass insanity, then Pheta Signi 12." "The last was Ingraham B, two years ago." "And next in line -- Deneva." "Bones, what's your theory about the cause of all this?" "There's no medical or scientific cause for what happened on those planets." "But it follows a definite pattern -- a systematic progression from planet to planet." "Captain, we're picking up a ship on our sensors, heading directly into the Denevan sun." "Plot an interception course, warp factor 8." "Lieutenant Uhura, try to contact that ship." "Aye, aye, sir." "Ship is a one-man vessel of Denevan configuration, Captain." "He does not seem to be out of control." "His course is straight for the sun." "Scotty, tractor beams?" "Out of range, sir." "[Uhura] Making contact, Captain." "Denevan ship, this is the U.S.S. Enterprise." "Can you reverse your course?" "Acknowledge." "[Static]" "Captain, we'll get too close to the sun." "Keep closing." "Denevan ship, reverse your course." "Do you hear me?" "Reverse your course!" "Acknowledge." "[Static]" "Outer hull temperature now 480 degrees and rising." "He's too close, Captain." "So are we." "Hull temperature 1,000 degrees and rising." "The sun's gravimetric pull increasing." "[Denevan Pilot] I did it!" "It's finally gone!" "I'm free!" "I'm " "He burned up, Captain." "Reverse course." "180 degrees about." "Aye, sir." "All clear, Captain." "Hull temperature falling, gravimetric pull approaching tolerance level." "Very well." "Reduce to sub warp speed." "Take us to Deneva." "Aye, aye, sir." "That Denevan ship headed deliberately into the sun." "Why?" "There's one possibility." "The mass insanity may have reached this planet, too." "Captain, I'm having difficulty on that transmitter call to Deneva." "Keep trying." "Yes, sir." "Jim, your brother Sam, his family, aren't they stationed on this planet?" "Space -- the final frontier." "These are the voyages of the starship Enterprise." "Its five-year mission -- to explore strange new worlds ... to seek out new life and new civilizations ... to boldly go where no man has gone before." "Captain 's Log -- star date 3287.2." "The mass insanity we have tracked across this section of the galaxy seems to have already touched Deneva." "That planet, colonized a century ago, is one of the most beautiful in the galaxy." "Planet development is normal, Captain." "Originally colonized as a freighting line base in this area." "They make regular trips from here carrying supplies to the asteroid belt for the miners and bringing cargo out." "I've made the run myself as an engineering advisor." "No Federation contacts for over a year." "Captain." "I've made contact with your private transmitter, sir." "Put it on audio." "[Woman] Please hurry." "Help us." "I don't have much time." "They'll know." "Please!" "Please help us " "Aurelan, this is Jim on the Enterprise." "Repeat your message." "Contact broken, sir." "Reestablish." "I'm sorry, sir." "I'm not interested in your excuses, Lieutenant." "Reestablish contact with that transmitter." "I'm afraid that's impossible at the moment, Captain." "They stopped broadcasting immediately." "They do not acknowledge my contact signal." "Keep trying to raise them." "Yes, sir." "Jim, did you know who that woman was?" "Yes." "You were right a while back." "My brother Sam lives on Deneva." "He's a research biologist." "That woman... sounded like his wife Aurelan." "Set your phasers on stun." "We're going to beam directly into the capital city." "Alert status." "Mr. Spock." "Lieutenant Uhura has had no further response to our signals." "Sensors report the expected number of humans on the planet surface." "However they are strangely quiet." "Very little activity." "I'll want a complete transcript of everything that happens down there." " Yes, sir." " Let's go." "Energize." "There are almost a million inhabitants of Deneva." "There's more than 100,000 in this city alone." "Where is everyone?" "They're here, Captain." "In the buildings." "Strangely quiescent." "My brother's lab is over there." "They signaled us once." "There should be someone there." "Let's find out what's happening." "[Shouting]" "Captain, several people approaching." "Go back!" "Get away!" "We don't want to hurt you!" "Go back!" "Get out of here." "Go on, get away!" " Go away!" " Get out of here!" "We don't want to hurt you." "Stand by to fire." "Fire." "Did you hear what they said?" "They seemed concerned for our safety." "They tried to brain us with these clubs." "Check them out, Bones." "Their attitude was inconsistent with their actions." "To say the least." "There's something wrong, Jim." "Their nervous systems -- unconscious like this, there should be just routine autonomic activity, but I'm getting a very high reading, as though even in their unconscious state, they're being violently stimulated." "[Woman Screams]" "Fan out." "Follow me." "Aah!" "Security." "Aah!" "They're here!" "They're here!" "Please!" "Keep them away!" "[Sobbing]" "They're here!" "They're here!" "Bones." "[Sobbing Subsides]" "Aurelan, you're safe now." "Is this your brother, Jim?" "Ohh." "Sam." "It is my brother." "Was my brother." "I'm sorry, Jim." "The boy's unconscious, but he's still alive." "Peter." "I better get the boy and the mother back to the ship." "I can't do much for them down here." "Get ready to beam up." "Calling Enterprise." "Prepare to beam up party of four." "Captain," "I understand how you must " "Yes." "Yes, Mr. Spock." "You heard my sister-in-law say something about they being here." "Your guess." "Notice the ventilator, Captain." "Apparently they were trying to keep something outside from getting in." "Obviously they were not entirely successful." "It doesn't make sense." "No harmful life forms were reported." "Our sensors didn't pick up anything that didn't belong here." "That is correct." "I am at a loss to understand it." "Ready to beam up." "I'd like you to be onboard when your sister-in-law regains consciousness." "Take charge of the landing party, Mr. Spock." "I want some answers to all this." "I won't be able to give you the exact cause until I get the plates back from the lab." "They're both in extreme pain." "I sedated them heavily." "Your sister-in-law has a high tolerance." "The tranquilizer hasn't affected her much." "Can she talk?" "Yes." "[Moaning]" "Aurelan." "Aurelan." "It's Jim." "Jim?" "Sam, he's..." "He's dead." "But your son's still alive." "You've got to help us." "You are here." "It is you, Jim." "Yes, I'm here." "You have to tell us what happened, Aurelan, to you and the others." "They came ... eight months ago." "Who?" "Things." "Horrible things!" "Visitors brought them in their vessel from another planet." "Ingraham B." "What kind of things?" "Not the ship's crew's fault." "The things made them bring their ship here." "Aurelan... it's important that you tell us ..." "What kind of things?" "Not their fault." "[Sobbing Loudly]" "When she answers questions, any questions, it's as if she's fighting to get the answers out, as though something is exerting pain to stop her." "They use it to control us." "They're spreading, Jim." "They need us to be their arms and legs." "They're forcing us to build ships for them." "Don't let them!" "Don't let them go any further!" "Aah!" "My brother's son?" "I'll do everything I can, Jim, to save him." "Report." "The streets are extraordinarily quiet." "We've seen no other Denevans, and the ones we stunned earlier were gone when we came out." "You've seen some kind of creature." "Any alien form?" "None, sir." "Just that noise we heard." "Peculiar buzzing sound." "We were about to investigate it." "All right." "Let's go find out what it is." "Set your phasers on force three." "To kill." "We're looking for some kind of creature, and we already know it will kill." "[Buzzing]" "[Squeak]" "[Buzzing Continues]" "[Squeak]" "Spock!" "[Squeak]" "Stay low." "Fire!" "Incredible." "Not only should it have been destroyed by our phasers, it doesn't register on my tricorder." "Captain, it doesn't even look real." "It's not life as we know or understand it." "It is obviously alive, it exists..." "And it can bear up under full phaser power." "I suggest we risk taking it aboard." "It may be a trap in here." "Let's move out." "Let's move out." "Spock!" "Spock!" "It's gone." "Can you stand?" "Spock, are you all right?" "Captain 's log supplemental." "Whatever the creatures are, they have apparently taken over all the inhabitants of Deneva." "Meanwhile, ship 's surgeon Dr. McCoy is examining a strange puncture wound left by one of the creatures on Mr. Spock's back." "Nurse." "That's the second time he's come out of it." "Either he's fighting us, or something inside of him is fighting us." "The readings have never looked like that before, not even on Mr. Spock." "Let's prepare to close." "Nurse!" "Doctor, that's not all you're going to do." "Miss Chapel." "Doctor, there is more of it in him, entwined all through his body." "If you cannot assist me as required, call another nurse in here." "But do one or the other now." "How is he?" "To be very frank, Jim," "I don't know that I can do anything for Spock or your nephew." "They're pieces of some form of living tissue." "I removed one from Spock's spinal cord, the other from your sister-in-law's body." "They're both the same." "The boy's too weak to touch." "Besides, removal of the tissue wouldn't stop the pain anyhow." "Did you operate on Spock in time?" "No." "I just removed these for examination." "His body's full of these tentacles, entwining and growing all about his nervous system." "My nephew?" "The same." "Evidently, when the creature attacks, it leaves a stinger much like a bee or wasp, leaving one of these in the victim's body." "It takes over the victim very rapidly, and the entwining is far, far too involved for conventional surgery to remove." "Recommendations?" "I'm sorry, Jim." "The lab, the science departments ..." "We're all stumped." "No!" "No!" "Mr. Spock." "No, I won't." "Mr. Spock " " Oh!" "Bridge, this is sick bay." "Tell Dr. McCoy Mr. Spock just left here." "He's delirious and possibly dangerous." "All decks, security alert." "Locate and restrain Mr. Spock." "He may be dangerous." "Use phasers on stun if necessary." "Must take the ship " "Down!" "I must ..." "Take it down." "Get him back to the sick bay." "Use security restraints." "The K-3 indicator registers the level of pain." "Watch as I turn it on." "That's what he's been going through." "I've never seen anything like it." "No wonder the poor devils go mad." "Dr. McCoy." "Captain." "Spock." "These restraints will no longer be necessary." "Nor will your sedatives, Doctor." "I'll be able to return to duty." "I apologize for my weakness earlier when I tried to take control of the ship." "I simply did not understand." "What is there to understand, Mr. Spock?" "I am a Vulcan, Doctor." "Pain is a thing of the mind." "The mind can be controlled." "You're only half Vulcan." "What about the human half?" "It is proving to be an inconvenience, but it is manageable." "The creature, with all of its thousands of parts, even now is pressuring me." "It wants this ship, but I am resisting." "Can he control it the way he says, Bones?" "Who knows, Jim?" "I know the amount of pain the creature can inflict upon him, but whether he can control it hour to hour ..." "I have my own will, Captain." "Let me help." "I need you, Spock ... but we can't take any chances." "We'll keep you ... confined for a while longer." "If you can maintain control, we'll see." "Uhh ..." "My nephew." "If he regains consciousness, will he go through that?" "Yes." "Help them." "I don't care what it takes or costs." "You've got to help them." "Jim, aren't you forgetting something?" "There are over a million colonists on that planet down there" "Just as much your responsibility." "They need your help, too." "I am a Vulcan." "I am a Vulcan." "There is no pain." "Mr. Spock." "I thought you were still confined to sick bay." "I was." "Here, now." "Where do you think you're going?" "I have an errand on the planet's surface." "You'll beam me down to the same coordinates as before." "Not likely, Mr. Spock." "That is an order, Mr. Scott." "Aye, sir." "I'm sorry I have to disobey it." "The captain said no one was to transport down." "Mr. Spock." "Freeze right there, Mr. Spock, or I'll put you to sleep for sure." "This is Mr. Scott in the transporter room." "Get me the captain." "I ordered you to stay in sick bay." "Until the pain was gone, Captain." "It has been discontinued ...by me." "Scotty?" "He said he was transporting to the surface." "Your orders were no one was to beam down unless you authorized it." "And knowing Mr. Spock's determination on some things," "I thought I'd hold him until I got your orders." "One of the creatures will have to be captured and analyzed." "We did not have a clear opportunity earlier when I was attacked." "Since my nervous system is already affected, as you pointed out, Doctor," "I don't believe they can do much more to me." "Jim, this is ridiculous." "I don't want my patients running around." "He should be in bed." "I am in complete control of myself, Doctor." "The fact that I am here proves that I do not belong in bed." "Mr. Spock ... your logic, as usual, is inescapable." "Beam him down." "Stay in constant touch with us." "Give him your phaser." "He'll need that, too." "Thank you, Captain." "Energize." "Jim, that man is sick." "Don't give me any damnable logic about him being the only man for the job." "I don't have to, Bones." "We both know he is." "[Buzzing]" "[Squeak Squeak]" "Come in, gentlemen." "I believe you'll find this interesting." "Doctor, your medical skill and curiosity are quite admirable, but I assure you I'm all right." "You may be controlling the pain, Mr. Spock, but you're far from all right." "Unimportant at the moment, Doctor." "Please observe." "Interesting, gentlemen." "A one-celled creature resembling, more than anything else, a huge, individual brain cell." "Yes." "That would answer a lot of questions." "Do you understand what I'm suggesting?" "I think so." "This may be one cell in a larger organism, an incredibly huge organism, in fact." "And although it's not physically connected to the other cells, it is, nevertheless, part of the whole creature, guided by the whole, drawing its strength from the whole, which probably accounts for its unusual resistance" "to our phaser weapons." "Existing so differently from any living matter or energy as we know it, that it may have come here planet by planet from an entirely different galaxy." "From a place where our physical laws do not apply." "We may therefore find it difficult to destroy, Captain." "But not impossible, Mr. Spock." "The Denevan that flew into the sun cried out that he was free, that he'd won." "That's the angle to work on." "I want an analysis of all this from Medical and Life Science departments within the hour." "Yes, sir." "I'm sorry, Captain." "I've tried everything I can." "Variant radiation, intense heat as great as 9,000 degrees." "Then you're wasting your time." "There has to be something that'll kill the creature without destroying the human host." "Which is my point." "The thing won't die, even at temperatures and radiation which would burn Spock and your nephew to ashes." "I can't accept that, Bones." "We've got 14 science labs aboard this ship." "The finest equipment and computers in the galaxy." "Captain ..." "I understand your concern -- your affection for Spock, the fact that your nephew is the last survivor of your brother's family." "No, no, Bones." "There's more than two lives at stake here." "I cannot let it spread beyond this colony, even if it means destroying a million people down there." "Captain 's Log." "Star date 3289.8." "I am faced with the most difficult decision of my life." "Unless we find a way to destroy the creatures without killing their human hosts, my command responsibilities will force me to kill over a million people." "Gentlemen." "I regret I see no other choice, Captain." "We already know this thing has destroyed three civilizations." "Perhaps more." "I want it stopped, too, but not at the cost of destroying a million people." "Including myself, Doctor, and Captain Kirk's young nephew." "Understandably upsetting, but once it spreads past here, there are dozens of colonies beyond and billions of people." "If killing 5 people saves 10, it's a bargain." "Is that your simple logic?" "I will accept neither of those alternatives, gentlemen." "I cannot let this thing expand beyond this planet, nor do I intend to kill a million people to stop it." "I want another answer." "I'm putting you gentlemen on the hot seat with me." "I want that third alternative." "Report." "Sorry, Jim." "We've been over and over it, made every conceivable test." "I therefore request permission to beam down to the planet's surface and that your nephew accompany me." "Request denied." "Captain ..." "I do not make this request lightly." "I do not know how much longer" "I can hold out against the pain." "But I do know what the boy will go through should he regain consciousness." "Request denied." "There must be another answer." "Something ... in the sun ... killed that thing before the Denevan died." "All right." "All right." "We've tried ...heat, radiation." "What other qualities or properties does the sun have?" "It exists physically." "It occupies space, it has mass, therefore, gravity." "It converts matter to energy." "[Pulsing]" "Jim, we've been through it and through it." "Radiation, heat ..." "But one other thing you haven't mentioned." "It's bright." "It radiates a blinding light if you're close enough." "Nothing lethal about light." "Not to us." "But down on the surface, the creatures stayed in the shadows for the most part." "Suppose ..." "they weren't simply hiding." "Suppose they're sensitive to light, light, like in a sun close up." "A possibility." "You can't move Deneva closer to the sun, Jim." "But you can move the sun's equivalent to Deneva!" "Mr. Spock?" "Yes." "In essence it can be done -- a string of satellites around the planet with burning trimagnesite and tritium." "[Sigh]" "Well, I can rig a test cubicle in a bio lab, put our specimen in it." "But I don't " "Good." "Let's get on it." "Your figures are, of course, accurate." "Of course." "The light of the sun at the proximity where the Denevan declared himself free was 1 million candles per square inch." "If this works, the satellites we orbit will produce light of such intensity that even someone in a closed, darkened area will be affected by it." "Ready, Doctor." "Put on your masks." "Completed." "It worked!" "We can do it." "What's the matter, Jim?" "We can do it!" "It worked." "In a lab." "With the creature exposed to everything we can give it." "But what about the people who are infected?" "Well, I don't know." "Maybe trial " "There's no time for maybes, Bones." "We need to know now." "But I'd have to put a " "Yes, we'd have to put someone who's infected under that light." "Do you have any idea of the risk?" "We have to duplicate the conditions on the planet." "And Spock ..." "Captain." "You'll need a host for the next step in the test to determine whether the creature can be driven from the body." "I am the logical choice." "Do you know what 1-million candlelight per square inch can do to your optic nerves?" "There's no other way, Bones." "We have to duplicate the brilliance that existed at the moment the Denevan declared himself freed." "All right." "I'll rig up a protective pair of goggles." "There'll be none on the planet's surface, Doctor." "I agree completely." "Unfortunately, you're both right." "It's the only thing we can do." "All right, Mr. Spock." "Mr. Spock's the best first officer in the fleet." "Proceed." "Completed." "Spock, are you all right?" "The creature within me is gone." "I am free of it ... and the pain." "And I'm also quite blind." "An equitable trade, Doctor." "Thank you." "Doctor, the results of the first tests on the creature's remains ..." "Oh, no." "What is it?" "I threw the total spectrum of light at the creature." "It wasn't necessary." "I didn't stop to think that only one kind of light might've killed it." "Interesting." "Just as dogs are sensitive to certain sounds which humans cannot hear, these creatures evidently are sensitive to light we cannot see." "Are you telling me ... that Spock need not have been blinded?" "I didn't need to throw the blinding white light at all, Jim." "Spock, I ..." "Doctor ... it was my selection as well." "It is done." "Bones." "Take care of him." "Completing the seeding orbit, Captain." "2 10 ultraviolet satellites now in position." "72 miles altitude." "Permanent orbit about the planet." "Good." "Scanners?" "Scanners ready, sir." "Very well." "Ready, Helm?" "Ready, Captain." "Satellite control, this is the captain." "Energize all satellites." "Affirmative." "All satellites operative, Captain." "Captain, receiving messages from our ground station." "Report." "The things are dying, sir." "It's working." "Sick bay." "McCoy here." "Tell Spock ... it worked." "Yes, Captain." "He'll be happy to hear that." "Bones ... it wasn't your fault." "Bones." "Bones." "Yeoman, record this for Starfleet Command." "Ready, sir." "The alien creatures on Deneva have been destroyed " "Captain, look." "Mr. Spock." "[Kirk] Spock." "You can see." "The blindness was temporary, Jim." "Something about his optical nerves which aren't the same as a human's." "An hereditary trait, Captain." "The brightness of the Vulcan sun has caused the development of an inner eyelid, which acts as a shield against high-intensity light." "Totally instinctive, Doctor." "We tend to ignore it, as you ignore your own appendix." "Mr. Spock." "Regaining eyesight would be an emotional experience for most." "You, I presume, felt nothing?" "Quite the contrary, Captain." "I had a very strong reaction." "My first sight was the face of Dr. McCoy bending over me." "'Tis a pity your brief blindness did not increase your appreciation for beauty, Mr. Spock." "If you gentlemen are finished, would you lay in a course for Star base 10, Mr. Spock?" "My pleasure, Captain." "Unusual eye arrangement." "I might've known he'd turn up with something like that." "What?" "I said, please don't tell Spock I said he was the fleet's best first officer." "Why, thank you, Dr. McCoy." "You've been so concerned about his Vulcan eyes, Doctor." "You forgot about his Vulcan ears." "Ahead warp factor 1, Mr. Sulu." "Warp factor 1, sir."
