Mythical muscleman Hercules (Lou Ferrigno) must rescue his true love and stop a band of rebellious gods from deposing Zeus in this fantastical double feature. In the first tale, Hercules battles monstrous foes when the evil Amazon Ariadne (Sybil Danning) kidnaps Hercules’ fiancée, Princess Cassiopea (Ingrid Anderson). In the second tale, the almighty Zeus will lose his power to despot gods unless Hercules can recover his stolen thunderbolts.
