That Which Survives ( episode ) " Enterprise " crew members are stranded on a ghost planet and terrorized by the image of a beautiful woman . Summary . Teaser . The investigates a planet whose size is approximately that of Earth ' s moon , yet mass and atmosphere are similar to Earth . Stranger yet is that it is apparently only a few thousand years old . Its geological age is much less than the indigenous vegetation and atmospheric content would indicate . Captain Kirk is intrigued by the unexplainable planet and organizes a landing party consisting of himself , Doctor McCoy , helmsman Sulu , and senior geologist . As the landing party steps onto the transporter platform and starts to transport down to the surface of the planet , a mysterious woman suddenly appears , telling them that they must not go . She then touches the transporter operator Wyatt who instantly crumples to the deck as the dematerializing landing party watches helplessly . She is too late to prevent the beam down , and moments later the four men materialize on the planet ' s surface . Once on the planet , Kirk attempts to contact the " Enterprise " with his communicator to report the attack , but before he can do so , a powerful tremor rocks the planet . At the same instant the " Enterprise " is tossed about in some sort of turbulence . Both disruptions subside simultaneously , and the crew of the " Enterprise " quickly discovers that the planet is no longer on the viewscreen . On the planet D ' Amato ' s tricorder reads an energy burst of almost immeasurable power . When Kirk is unable to raise the " Enterprise " on his communicator , Sulu discovers that the " Enterprise " is missing from orbit , effectively stranding the landing party on the planet . Act One . The landing party is at a loss to explain the sudden disappearance of the " Enterprise " . Sulu conjectures that the " Enterprise " must have blown up , citing high radiation readings as evidence of a matter / antimatter intermix explosion . Kirk quickly dismisses Sulu ' s theory due to a lack of residual radiation . McCoy then suggests that the " Enterprise " may have crashed onto the planet itself . Neither of these theories fits the facts . Recognizing that regardless of the " Enterprise " s fate , the landing party will soon need food and water , Kirk orders a detailed analysis of the planet ' s resources . The report is not encouraging , as all plant vegetation on the planet is poisonous to Humans , there is no evidence of rainfall or surface water and the only other form of life is a virus - like plant parasite . During the survey , Sulu makes a sweep with his tricorder and registers a sudden magnetic reading that quickly dissipates , like a door opening and then closing again . McCoy also detects a powerful lifeform reading that appears and then disappears . These fluctuations occur as the same woman who appeared in the transporter room of the " Enterprise " confronts D ' Amato , killing him with her touch . McCoy reports that all the cells of D ' Amato ' s body have been disrupted from the inside . Kirk attempts to dig a grave for the geologist with his phaser , but the surface of the planet withstands its force . Further investigation reveals that the planet is an artificial body . In the meantime , the crew of the " Enterprise " attempts to discern what had happened . Scott reports no damage to the ship ' s engines . Uhura reports that the ship is functioning normally and there are nothing more than bumps and bruises as a result of the turbulence , save one casualty : transporter officer Wyatt has been found dead . Doctor M ' Benga reports that they are not yet sure of the cause of death , as Dr . Sanchez is in the middle of Wyatt ' s autopsy . Spock orders Scott to have the transporter checked for malfunctions . Helm officer Lieutenant Rahda notes that there is no debris , which would have been left over from a planet breakup . She then reports that the position of the star s have changed . She verifies her findings by replaying a recording of the stars made just prior to the turbulence on the viewscreen . Spock is able to interpolate that , in a manner of seconds , the " Enterprise " has somehow been thrown 990 . 7 light year s from its previous position . The preliminary autopsy on the transporter officer comes in and the causes of death appears to be cellular disruption , as if every cell in the body had been blasted from inside . Spock orders that the " Enterprise " return to the planet at top warp speed , which turns out to be warp factor 8 . Act Two . Although the ship did not appear to suffer any damage , chief engineer Montgomery Scott is disquieted , and reports that the ship feels " wrong . " Spock initially dismisses this as emotional . Still concerned , Scotty instructs crewman Watkins to check the bypass valve on the matter - antimatter reaction chamber to ensure that it is not overheating . While Watkins is doing so , the woman appears in the control room and inquires about the engine mechanisms . She then kills him in the same manner as the others . Before Watkins dies , he cries out a warning about the intruder to Scott , but she disappears before Scott can see her . Back on the surface of the planet , Sulu volunteers to keep watch while Kirk and McCoy sleep . While the captain and the doctor sleep , the woman appears to Sulu and , although she is able to briefly touch him , disrupting all the cells his shoulder , she does not kill him . Sulu yells out for help and Kirk and McCoy run to his rescue . Sulu cries out not to let her touch them . The woman insists that she is for Sulu and that she must touch him . When she touches Kirk on his shoulder , however , nothing happens . Kirk asks how she can destroy others and she explains that she does not want to destroy . She then disappears . The landing party surmises that the woman ' s destructive power can only be directed at one specific person at a time . Act Three . Aboard the " Enterprise " , which is warping back to the planet , the ship ' s engines begin to race out of control . Scotty discovers that the emergency overload bypass of the matter - antimatter integrator has been fused , although it would have taken all the power of the ship ' s phasers to do so . It becomes apparent that the woman is responsible for this sabotage . With this damage , the " Enterprise " has less than fifteen minutes before its engines will explode . Spock and Scotty devise a risky plan to save the ship – Scotty will enter the crawlway leading to the matter - antimatter reaction chamber and attempt to manually shut off the flow of fuel with a magnetic probe . Scotty installs explosives at the end of the service crawlway that will permit Spock to jettison the pod if Scotty ruptures the magnetic bottle . Recalling Scotty ' s earlier assertion that the ship felt wrong , Spock runs an analysis comparing the condition of the " Enterprise " with its ideal condition . When the woman reappears to kill Kirk , the landing party is able to use this information to defend him . Kirk questions her with McCoy and Sulu keeping her at a distance . She calls herself Losira , commander of the station . When Kirk asks how she feels about killing him , she says that the act of killing is wrong but that she must do so . She says that she is sent to defend the station , although the people who once lived on it are no more . Kirk presses her , sensing her confusion and loneliness , and she disappears again . Following their tricorder readings , the landing party eventually finds an underground door to the planet - station . Spock ' s analysis proves crucial , for he has discovered that the " Enterprise " has been put through a molecular transporter and then reassembled slightly out of phase , which will require Scott to reverse the polarity on the magnetic probe in order to seal the incision . Scott attempts to do so as the final seconds tick down , but the mechanism on the probe becomes jammed . Scotty insists multiple times to Spock that he jettison him , but Spock gives him a few seconds more . Scotty is able to loosen the tool and , just moments before the engines go critical , accomplishes the task and the " Enterprise " finally begins to slow down . Act Four . On the planet , the landing party enters a computer room , where they are confronted with three versions of the destructive woman , each programmed to kill one of them . The landing party seems to be out of options when Spock and a security officer materialize into the room and Lemli destroys the computer with his phaser . The women disappear and are replaced by a recorded image of Losira . In the recording , Losira welcomes her fellow Kalandan s to the colony . She explains that the population of the colony has been destroyed by a disease that they accidentally produced when they created the planet . Losira is the last survivor , and because she does not believe she will survive until help arrives , has set the station defense mechanism on automatic to defend against other life forms . McCoy surmises that the entire species was destroyed by the disease , and that the image of Losira has been waiting thousands of years to deliver her message to a people who have become extinct . It is apparent to the landing party that the computer defense mechanism called upon the only image available , that of Losira , but the replication was too perfect and projected so much of her personality that it felt regret and guilt at killing . They agree that she was a remarkable and beautiful woman . Spock says that beauty is transitory , but Kirk disagrees , saying " " beauty survives " " . Memorable quotes . " " What is it , Jim ? " " " " A planet that even Spock can ' t explain . " " " " What happened ? " " " " The occipital area of my head seems to have impacted with the chair . " " " " No , Mister Spock . I meant what happened to us ? " " " " Mister Sulu , if I ' d wanted a Russian history lesson , I ' d have brought along Mister Chekov . " " " " Can you give me warp eight ? " " " " Aye , sir . And maybe a wee bit more . I ' ll sit on the warp engines myself and nurse them . " " " " . . . That position , . . . Mister Scott . . . would not only be unavailing but also . . . undignified . " " " " I am only for D ' Amato . " " " " Lucky D ' Amato . " " " " What a terrible way to die . " " " " There are no good ways , Sulu . " " " " Mister Spock , the ship feels wrong . " " " " It looks so lonely there . " " " " It would be worse if he had company . " " " " Mister Scott , there ' s a strange woman who knows the entire plan of the " Enterprise " ! " " " " Well , your guess is as good as mine . " " " " My guess , Doctor , would be valueless . " " " " Stop or I ' ll shoot ! I don ' t want to have to kill a woman ! " " " " How can such people be , Captain ? Such evil and she ' s so , so beautiful . " " " " Mister Spock , what are the chances of the captain and the others being alive ? " " " " Lieutenant , we are not engaged in gambling . " " " " This thing is going to blow up , and there ' s nothing in the universe can stop it . " " " " You ' ll be killed , man ! " " " " Unless a solution is found quickly , that fate awaits all of us . " " " " I ' m so close to the flow now it feels like ants crawling all over my body . " " " " I know what time it is . I don ' t need a bloomin ' cuckoo clock . " " " " You might at least say thank you . " " " " For what purpose , Mister Scott ? What is it in you Humans – " " " " Never mind . " " " " Beauty is transitory , Doctor . " " " " Beauty survives . " " Background information . Remastered information .
