This leads to the day Hercules is born to Zeus and Hera, much to the pleasure of the other gods except Hades, who receives word from the Fates that Hercules will one day rise to power and prevent him from taking control of the world.
The film begins with the five muses, 'Goddesses of the arts and pro-claimers of heroes', telling the story of how Zeus came to power and prevented the monstrous Titans from ruling the world.
