Hercules, having agreed to restore justice to Mycenae, confronts evil Prince Myles. The villain is invested with power over giant bronze warriors by his mother Pasiphaë, a sorceress in Hades. Myles assassinates the king and abducts his cousin, Queen Ate, through whom he plans to inherit the throne. Although Zeus temporarily removes Hercules' strength for killing Eurystheus, an innocent man framed by Myles, the god restores his powers. Hercules then saves Ate and destroys Myles, Pasiphaë, and the giant warriors.
