Jason, a fearless sailor and explorer, returns to his home land of Thessaly after a long voyage to claim his rightful throne. He learns, however, that he must first find the magical Golden Fleece. To do so, he must embark on an epic quest fraught with fantastic monsters and terrible perils.

Don Chaffey's Jason and the Argonauts is an outlandish, transportive piece of nostalgia whose real star is the masterful stop-motion animation work of Ray Harryhausen.
