According to Memory Alpha's original in Universe Timeline, the story sequence is:
Day of the Dove : That Which Survives : A Piece of the Action.
In the Remastered Episodes Chronology, the release sequence is
By Any Other Name : That Which Survives : Is There in Truth No Beauty?.


After Kirk, McCoy, Sulu and the geologist D'Amato have beamed down to a seemingly uninhabited planet, the Enterprise is hurled away almost 1000 light years. While they are left on their own on the planet, a woman first comes and kills D'Amato, then reappears and hurts Sulu. Each time this woman called Losira appears, she is capable of killing just a single specific crew member.

Meanwhile on the Enterprise, the woman has killed two more of the crew and sabotaged the ship's engines to blow up. In a race against time Scott and Spock manage to repair the damage. Kirk, McCoy and Sulu find the entrance to an underground habitat, where they are facing three copies of Losira, each programmed for one of them. Spock beams down with a security officer, who disables the computer that controls Losira.

It turns out that the planet is an artificially constructed Kalandan outpost, whose population died long ago because of a deadly virus that may have been spread to other colonies and erased the civilization.

Errors and Explanations

The Nitpicker's Guide for Classic Trekkers

Plot Oversights

  1. After conducting a “detailed” analysis of the planet, the landing party reports back to Kirk. They have a meeting, and the captain decides that finding water is one of the highest priorities. He sends D'Amato out to look for an underground source. Wouldn't a detailed analysis of the planet include this information? The initial analysis may have only been able to collect information about the surface.
  2. Kirk does an amazing job on the headstone of D'Amato’s grave. It is nicely square and has “LT. D'AMATO" written on it. A few moments earlier, the episode demonstrated that the rock on the planet was almost impossible to cut with a phaser. How, then, did Kirk create this object to begin with? Perhaps Kirk and Sulu used their phasers in combination to cut the rock, by merging the beams.
  3. After his first encounter with Losira, Sulu is amazed that someone so beautiful could be so evil. Didn't we just have an episode on this topic? Wasn’t this one of the main themes of Is There in Truth No Beauty?. ls Sulu not paying attention? Or did he not watch the reruns of the visual logs on the viewscreen's late night entertainment channel? Kollos and Miranda, the guests aboard Enterprise in Is There in Truth No Beauty?, were not inherently evil.
  4. After sending the Enterprise on its distant trip, the defensive computer on the planet programs a copy of Losira to sabotage the engines. Careening madly through space, Spock estimates that the ship and crew have only “14.87 minutes” left and relays this information to Scott. Moments later, he tells Scott they have "12 minutes and 27 seconds" left. Wouldn’t it be better to standardize a format for telling time so that the crew doesn't have to convert mentally to the format they prefer? This could be a matter of personal preference.
  5. To fix the problem with the engines, Scott must fiddle with the magnetic containment field that holds the antimatter. After the process begins, Spock tells Uhura to monitor the magnetic force. He orders her not to take her eyes off the indicator. Of course, the entire time he’s giving her these instructions, she’s looking at him and not at the instruments! She will start monitoring the instruments as soon as Spock has finished giving her his instructions, and not before! (Besides, it is generally considered ill-mannered to avoid looking at someone when they are talking to you!)
  6. This episode has to be a first. To my recollection, this is the first time Kirk has actively refused the affections of a beautiful alien woman. She keeps saying, “I must touch you. I am for you," and our beloved captain keeps telling her, “No, no. That's okay." (l suppose the prospect of dying would have the same effect as a cold shower.) He's probably realised that Losira was responsible for the death of D'Amato and the attack on Sulu.
  7. As Scott begins his repairs, Spock tells him he has 8 minutes and 41 seconds left. The action then shifts to the planet and finally back to the Enterprise. Soon afler returning, Spock tells Scott he has 57 seconds left, and the scene shows Scott holding the same doohickey that he held before we went to see what was happening on the planet. What has this guy been doing for almost 8 minutes? He may have been using it during the repairs.
  8. Alter all the dramatic countdown and tension of the imminent destruction of the Enterprise, the deadline comes and goes and nothing happens. If Spock is so precise in his calculations, why was Scott able to work for several seconds after the Vulcan said the ship would explode? Scott's actions may have delayed the explosion long enough for him to complete the repair work.

Changed Premises

  1. At one point, Uhura asks Spock what the chances are that Kirk and the others are still alive. The Vulcan rebuffs her, stating that they are not involved in gambling, that they are merely pursuing the only logical course of action. Suddenly Spock doesn't want to calculate odds‘? Isn't this the same guy whose mother had to shut him up because he wanted to give her the odds on his father's survival in Journey to Babel? Either he doesn't want to jeopardise crew morale by verbalising the possibility of Kirk and McCoy dying, or the slap from his mother put him off!

Equipment Oddities

  1. Several times during the show, Spock fiddles with a hand-held control mechanism. Oddly enough, it is the same device McCoy used in Spock's Brain to control the movements of the Vulcan when his mind was missing. To me, this episode offers the most convincing proof that McCoy didn't get Spock's brain wired back in correctly. The poor Vulcan has to carry around the control mechanism to access-the portions of his brain that our good doctor left unhooked! More likely this is an identical looking piece of equipment, which is used for some other purpose.
  2. When Losira “comes” for Kirk, McCoy tries to take a reading on her. He says she shows no life signs. There is not even a mechanical signature. Yet earlier in the episode, when Losira attacks D’Amato, McCoy registered “a life form reading of tremendous intensity," and a biological one at that. Either the earlier life form reading was faked, or Losira's life signs could have been masked after the initial encounter.

Continuity and Production Problems

  1. After D'Amato dies, Kirk attempts to dig a grave tor him using a phaser. The first shot has little effect, and the captain tries a second time. Touched by the phaser’s beam, the surface explodes and starts a little fire. The only objects in the immediate area of the blast are rocks and dirt. If l recall correctly, neither of these usually burn.There could be molecules of flammable materials in the dirt.

Internet Movie Database

Character error

  1. Left in charge of the ship, Mr. Spock uncharacteristically browbeats everyone on board just for being human (seemingly not free of emotions as he's always claimed). Given that he's the science officer and that the Enterprise orbits a planet whose very existence is inexplicable, it's reasonable to hypothesize that he's getting back at Kirk for leaving him out of the away mission by belittling the crew at every turn, thereby becoming a character ruled by the emotion of bitterness.He probably thinks he should be in charge of the landing party, as his scientific skills would be more useful.

Revealing mistakes

  1. During the opening "earthquake/storm" scene (as soon as landing party beams down), when the lightning flashes distinct shadows can be seen on the "sky" behind the rocks, emphasizing the fact that it is a fabric backdrop/screen. Remember this is an artificially created outpost.[N 2]

Nit Central

  1. D.K. Henderson on Sunday, December 20, 1998 - 10:24 am: I distinctly heard Kirk refer to the transporter officer as "Ensign". Spock refers to him as the transporter officer. Kirk later refers to him as the transporter chief. An Ensign for a Chief? He may have recieved a field commision.
  2. Losira does not want them on the planet; so why did she toss the ship away so that the four were stuck? A simple warning to go away might have sufficed. It was too late - they were already beaming down when she first appeared.
  3. McCoy with his trusty medical tricorder is able to determine in a moment what took an autopsy on the Enterprise. Either practice or a special add-on program for the tricorder.
  4. It was convienient that they beamed down right in the vicinity of the door to the complex. They probably detected it on the initial pre beam down scan.
  5. Losira spoke of a disease, and McCoy mentioned a virus. Did anyone think to check to see if they were infected as well before returning to the Enterprise? tim gueguen on Sunday, February 25, 2001 - 8:30 pm: I doubt the virus would be much of a worry. No one has lived on the planet for several thousand years, so the virus would have no way of surviving, assuming of course it effects Earth humans and Vulcans in the first place.
  6. mike powers on Sunday, March 16, 2008 - 3:19 am: Why couldn't Kirk, McCoy or Sulu do something with their own phasers once they were confronted by the 3 versions of Losira? Todd Pence on Sunday, March 16, 2008 - 8:05 am: Kirk and the others no longer had their own phasers. They were destroyed earlier in the episode.


  1. According to the episode list, the provisional stardate for this episode is 5683.
  2. A number of novels state this outpost is connected to the Iconians.
