The film begins in the present, with its heroine, Kaoru, a grown-up woman working as a real-estate agent, while helping out the folksy proprietor of a neighborhood fishing pond. There she meets a shy girl who needs her help baiting a hook and reminds her of herself in the fourth grade.

The story follows Arion, a young man kidnapped by Hades as a child and raised to believe that his mother was blinded by Zeus and that killing the ruler of Mount Olympus will cure her.
