The Legend of Hercules

In 1200 BC ancient Greece, King Amphitryon of Tiryns invades Argos. Amphitryon eventually fights rival King Galenus in personal combat, killing Galenus and seizing his kingdom. Queen Alcmene is disgusted by her husband's thirst for power and warmongering. She prays to Hera for guidance and Hera, wife of Zeus, tells her that she will allow Zeus to impregnate Alcemene with the savior of her people, a demi-god son to be named Hercules. The only other witness to this is Chiron, the queen's loyal adviser. Amphitryon names his new "son" Alcides, though Alcmene secretly acknowledges his true name as Hercules.
