Hades is the ruler of the underworld. Many years ago he was actually exiled by his older brother Zeus in the depths of Hell and now intends to catch up, gathering an army of monsters to capture the Olympus. The only one who can prevent Hades is the son of Zeus, the young Hercules, so the villain's henchmen kidnap the baby and turn it into a mere mortal. Many years later, the young man learns about his origins and aims to return home, but that he will have to perform many feats and become a true hero. But, as it turns out, even a victory over the forces of evil are not enough to return the divine origin.
