Hercules grows up feeling like he doesn't belong and goes on a journey to find his true identity. When he discovers that he is the son of Zeus, he is told that the only way he can regain entry to Mount Olympus is to become a true hero.
So with the help of Phil, a satyr, and Pegasus he begins training to become a hero. He ends up meeting Meg, a young woman who sold her soul to Hades, and falling in love with her. Meg is torn between loyalty to Hades and her growing love for "Wonder Boy".
When Hades strikes a deal with Hercules to give up his strength for 24 hours, Hades frees the Titans to take over Olympus. Due to one technicality in the deal, Hercules regains his strength and defeats Hades. But when he learns of Meg's death, he strikes a deal with Hades to rescue her and take her place in the underworld.
A little bit too modern for a story set in Ancient Greece but this movie contains all the essential elements of a true Disney classic.
