Spock’s court-martial board views the video stream from Talos IV of Captain Pike’s imprisonment 13 years earlier and of the Enterprise’s attempts to rescue him. The Talosians, using their powers of mind-reading and illusion, place Pike in worlds from both his memory and his imagination. The one constant is Vina, the beautiful blonde survivor of a crashed Earth ship (the other half of a Talosian plan for a captive Adam and Eve). Number One’s attempts to liberate Pike result in her and Yeoman Colt’s capture (additional breeding stock for the Talosian plan), but when the humans and Talosians learn more of each other, the situation takes a turn neither side expects. As the Enterprise approaches Talos IV once again, Kirk and the court watch the past unfold and learn the real reason for Spock’s mutiny.
