Hercules battles an evil sorceress who turns men into werewolves. The mythic duo returns in Prisoner of Evil, where a sorceress seduces Herc and transforms him into a mindless beast. Italian horror master Antonio Margheriti directed this installment of the Hercules legend, a blend of sword-and-sandal fantasy and horror.
