As Kirk, McCoy, Sulu and geologist D'Amato beam over to a geologically unique planet, an attractive woman suddenly appears in the transporter room and, with but a touch, kills Transporter Chief Wyatt. They're not quite sure who or what she is. They also find themselves unable to contact the Enterprise, which has been flung nearly a thousand light years across the galaxy. The woman soon re-appears, both on the Enterprise and on the planet, touching/killing D'Amato and Engineer Watson. While the landing party faces extermination from this mysterious woman, the Enterprise, endeavoring to return, faces possible destruction from a subtle malfunction administered to their warp engines.

After D'Amato dies, Kirk uses his phaser to dig a grave for him. This is only the second time on Star Trek where a crewman is buried by the landing party on a planet, the first occurring in The Galileo Seven. Usually, dead crewman are returned to the ship. See more
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.

But you are my match, James Kirk. I MUST touch you.
