Charles Evans, the lone survivor of a crashed colonizing expedition to the planet Thasus, comes aboard the U.S.S. Enterprise from the S.S. Antares. But when the Antares' Captain Ramart contacts Kirk in regards to Charlie, the Antares suddenly explodes.
Charlie shows not only a lack of grief for the people who had become his benefactors, but almost an indifference toward their deaths. He seems only concerned that his new "family" like and accept him. Unfortunately, teenage hormones and an isolated upbringing make that difficult.
Strange events occur whenever Charlie is angered: He makes Yeoman Rand disappear when she rebuffs his advances, he breaks Spock's legs when the Vulcan tries to discipline him, and he causes injury and discomfort to anyone who he thinks is laughing at him.
Eventually, Charlie demands that the Enterprise take him to the nearest inhabited planet, but Kirk fears that Charlie's uncontrolled temper and dangerous powers will create havoc for any civilization. Charlie gains control of the ship, but Kirk shortly overcomes him. Suddenly, an alien face appears on the bridge. It is that of a Thasian, the race who raised Charlie and gave him his psionic powers.
The Thasians realized that Charlie left their planet, and thus sent their own starship to intercept the Enterprise. Despite Charlie's tearful pleas to remain, the Thasians take the lonely child back to Thasus. Before they depart, the beings restore the U.S.S. Enterprise and her crew to normal.
