Jason seeks the Golden Fleece and returns home with a crew of adventurers to reclaim his birthright.

It's the time of Ancient Greece, 2000 B.C., and the city of Iolcus is under attack. Jason is only three years old when his uncle, evil tyrant Pelias, kills his father King Aeson, the popular ruler of Iolcus, and claims the throne. Furthermore, Pelias marries Jason's mother, Queen Polymele. Fortunately, Jason is rescued from certain death and taken away from Ioclus to be raised.
