As there is no agreement, Androcles King of Thebes seeks the assistance of his friend, the legendary Hercules. Hercules, now married to Deianira with a son named Hylas, does not wish to leave the comfort of his family, though Hylas is keen for adventure.Androcles takes matters in his own hands by drugging and kidnapping Hercules and placing him aboard a ship manned by a disreputable collection of former slaves and criminals. The only members of the expedition Androcles can trust are his sidekick, Timoteo the dwarf and Hylas who has to hide below deck from Hercules lest he face his wrath for leaving home. Rather than being angry Hercules merely lazes away on deck without offering any assistance. ........
