杰逊王子(伊阿宋)率领一批人去寻找传说中的金羊毛。在寻宝的过程里,杰逊必须击败一大堆可怕的对手:包括七头怪蛇、战斗骷髅、残忍的女头怪鸟以及所向无敌的铜神。Jason has been prophesied to take the throne of Thessaly. When he saves Pelias from drowning, but does not recognize him as the man who had earlier killed his father, Pelias tells Jason to travel to Colchis to find the Golden Fleece. Jason follows his advice and assembles a sailing crew of the finest men in Greece, including Hercules. They are under the protection of Hera, queen of the gods. Their voyage is replete with battles against harpies, a giant bronze Talos, a hydra, and an animated skeleton army, all brought to life by the special effects wizardry of Ray Harryhausen.
