Kintaro has challenged the local swimming coach (and former Olympic athlete) to a race, but he first needs to learn how to swim. While training, however, his situation with the coach, Ayuko Hayami is compromised.

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.
