A jewel-encrusted chalice is removed from its place of honor in the town of Parthus, bringing down the wrath of the gods in the form of a terrible rock storm. Hercules (Kevin Sorbo), guided by an all-wise Seer (Norman Forsey), tries to shepherd a group of refugees through the storm and into the safe harbor of Calydon. Though he confronts such obstacles as a treacherous swamp and a hugh pterodactyl, Hercules eventually discovers that the biggest threat to the safety of the refugees is their own leader, the shifty Broteas (John Sumner).
