Enterprise responds to a distress call at planet Rana IV, which was reportedly under attack by an unknown ship. But by the time they get there, the enemy is gone—along with all life and buildings on the surface. Eleven thousand colonists have been wiped out. No wait, make that 10,998. Scans show that there are two survivors located in an improbably intact square of land that contains a house and plant life.
