The USS Enterprise enters the C-111 system after receiving a 100-year-old distress call from the USS Archon. After entering orbit of planet Beta III, Captain Kirk sends a landing party down to the planet to investigate.

When the first party begins to exhibit strange behaviour, Kirk personally leads a second party down to the planet. The party discovers that the inhabitants are a controlled people, controlled by the lawgivers and are part of "The Body", which is all overseen by a man named Landru. The people are like pleasant zombies until the Red Hour strikes, enveloping the people in a twelve hour orgy of violence and emotional outbreak.

While Kirk and the landing party are investigating, the Enterprise is slowly being pulled out of orbit of Beta III to be absorbed by "The Body", which is what happened to the Archon a century earlier.

On the surface, Kirk discovers that the survivors from the Archon formed an underground group to resist "The Body", and Kirk manages to contact their descendants, and arranges their help to destroy Landru. Upon finding Landru, they discover that Landru is a highly sophisticated computer that was built 6,000 years earlier. The original Landru, a respected philosopher, only wanted to guide his people to become peaceful and civilized. While Landru had programmed the computer with his intellect, it didn't have his wisdom, and over the centuries the computer interpreted Landru's instructions literally and didn't allow anyone to show independent thought.

Kirk persuades the computer that it has destroyed Betan society and that it had failed in its objective, prompting the computer to destroy itself. The people of Beta III are now free, and Kirk arranges for Federation assistance in putting the planet back together again.
