Karen travels around the country with her husband Toru, visiting theaters all over the country. On her way home from work, she meets Keisuke, a young man who lives next door, and invites him over to her house. Keisuke is curious about the strip costumes hanging out to dry in the room, but Karen lies and tells him that her job is just dancing. The next day, without noticing Keisuke at the theater, a black-and-white show begins and Karen climaxes. Keisuke is confused by the lewd appearance of the beautiful young wife who has Kokoro, but when he finds out that Karen is leaving, he goes to the theater on the last day and takes on the forbidden live board show.
