Visiting Dr. Coleman and the ailing Dr. Lester, a colleague of Kirk's from Starfleet Academy who has always envied him due to her inability to achieve a captaincy in a male-captains-only Starfleet, Kirk is rendered unconscious by Lester. It turns out to have been a trap, and Lester puts herself and Kirk into an unknown device that transfers their minds into one another's bodies. Lester, in the form of Kirk, doesn't have time to kill Kirk (now in the female body). Lester and Coleman make every attempt to leave Kirk on the planet, but must bring "her" aboard to save face.
