In this melange of characters and events from separate mythological stories, Hercules, demigod and superman, arrives in the ancient Greek kingdom of Iolcus to tutor Iphitus, son of king Pelias; immediately on arrival, he falls in love with the king's delectable, briefly clad daughter Iole. Before he can win her, he must succeed in a series of quests, in the course of which he teams up with Jason, true heir of Iolcus, whom he accompanies on the famous voyage of the Argonauts.
