Captain’s log. The Enterprise arrives at the colony on Omicron Ceti III. The planet is bathed in Berthold rays, a form of radiation that is new to the Federation, so they don’t know its full effects, but extended exposure disintegrates living tissue. It is unlikely that there are any survivors of the colony—led by Elias Sandoval—a likelihood that is increased by the complete lack of response to Uhura’s hails.
However, Kirk beams down a landing party—Spock assures him that limited exposure is safe—including himself, Spock, McCoy, Sulu, DeSalle, and Kelowitz. The settlement is intact, but there’s no sign of any habitation. Kirk waxes rhapsodic on the tragedy of these people travelling all this way, including a year in space to reach the planet, only to die.
And then three people from the colony, including Sandoval, show up alive and well, and doesn’t Kirk feel foolish? Sandoval thinks they came because their subspace radio is on the fritz.
