Working as a campaign staffer for a mayoral candidate, Kintaro is assigned to tutor his boss' attractive teenaged daughter, Naoko Katsuda, who wants more from him than help with her math homework.

Kintaro becomes a servant in a traditional-style mansion of a wealthy family, but is quickly dismissed. He then challenges the daughter Reiko Tarayama, who abhors men and has a fetish for her motorcycle, to a race.
