While the U.S.S. Enterprise orbits planet Beta Three in Star System C-111, investigating the disappearance of the starship Archon there 100 years ago, Lt. Sulu returns from a scouting mission in an altered mental state, and Lt. O'Neil is missing on the planet. Captain Kirk leads a landing party to the planet, whose inhabitants live in fear of Landru and his law-givers.
The Archon crew was absorbed into "the body" -- a population with no free will, controlled by Landru through mind-control technology. Captain Kirk learns that Landru has been dead for six thousand years, and that a computer has been controlling the population for millennia. Kirk convinces Landru's computer that the stagnant population has no free will or creativity, so the computer destroys itself for the good of the planet it was designed to protect.
Sociologist Lindstrom remains behind with a party of experts to help restore the planet's culture, now that free will has been restored.
Factoid: Landru's mental influence cannot be broken by a Vulcan mind-meld.
