While approaching planet Pollux Four in the Beta Geminorum system, the U.S.S. Enterprise is captured by a force field shaped like a giant human hand. After reporting the situation to Starbase Twelve, the crew is contacted by the planet's inhabitant, who claims to be the Greek god Apollo.
Apollo invites Captain Kirk and other officers down to the planet, where he demands that they worship him as the Greeks once did. Apollo -- along with his fellow Olympians including Zeus, Hermes, Athena, Aphrodite, Hera, and Artemis -- visited Earth 5,000 years ago, but the others returned to the Cosmos while Apollo alone waited for humans to reach the stars one day.
Captain Kirk and the other officers refuse to worship Apollo, and the Enterprise crew manages to penetrate the force field holding the ship and uses the ship's phasers to destroy Apollo's temple, which generates his power. Realizing that humans will no longer worship him, Apollo returns to the Cosmos to join his fellow gods.
