While investigating the disappearance of the USS Archon on the planet Beta III, Kirk and his crew encounter an old-style Western community brainwashed and subservient to a sinister godlike figure called Landru.

A dark sense of foreboding falls over the crew of the USS Enterprise when the deserted hulk of their sister ship is found orbiting Omega IV. On board, Kirk discovers the crew's uniforms covered with a strange white powder, and tracks down a starship captain on the planet surface.
