Hercules (Reg Park) must battle a monster made of stone, retrieve a golden apple from the tree of Hesperides and brave the horrors of Hades to rescue his beloved from the clutches of the evil Lyco (Christopher Lee). Oracles, witches and vampires abound in this delirious 1960s blend of sword-and-sandal adventure, horror and psychedelia from Italian filmmakers Mario Bava and Franco Prosperi.
