Captain’s log. The Enterprise picks up an Earth-style SOS from a planet that is a dead ringer for Earth. Kirk beams down along with Spock, McCoy, Rand, and two security guards. They find abandoned buildings and vehicles, but no life. They find a tricycle, and McCoy futzes with it—only to be attacked by a scab-covered creature. Kirk and Spock manage to subdue him, and then he starts crying because the tricycle is broken. The creature has a seizure and dies. McCoy’s readings indicate that his biochemistry is acting like he’s aged a century in a few minutes.
They hear noises in a building, so they investigate. They check a closet, where Kirk—while standing with a phaser surrounded by several other people with phasers—says to come out because they mean no harm. They find a young woman named Miri in the closet, crying, begging them not to hurt her.
