Aries is desperate to leave the Greek Underworld so he can find his beloved fleece, and when he gets a chance to return to Earth, he takes his best friend Alex, the Underworld zookeeper, along for the ride. They soon discover the Golden Fleece is in the clutches of the evil immortal sorceress Medea - now a world-famous fashion designer. With the help of Rose, a twelve-year-old human girl, Aries and Alex must save the world from Medea's wicked plans . . . and save Aries from an eternity of being bald.
