As Adm. James T. Kirk (William Shatner) and Capt. Spock (Leonard Nimoy) monitor trainees at Starfleet Academy, another vessel from the United Federation of Planets is about to try out the planet-creating Genesis Device in a seemingly deserted portion of space. In the process, two of Kirk's officers are captured by Khan (Ricardo Montalban), an enemy Kirk thought he'd never see again.
