Naoko, female art teacher suffering from bipolar disorder spends her time at home compulsively chopping cabbage. She occasionally then begins cutting herself, causing her husband, Yoshio, to intervene. Yoshio attempts to help Naoko by dressing as a woman, "Yoshiko", in whom Naoko can confide. Yoshio has a low sex drive, and hopes to stimulate his interest by having Naoko dress as a school girl. When so attired, shopping for appropriately adolescent socks, Naoko meets Kimiko, one of her female students. Kimiko's parents have abandoned her, and she stays with a strange man named Tokio. Naoko suggests that Kimiko come to live with her. At their home, Kimiko proceeds to seduce both Naoko and her husband. During a sex session with Yoshio, she binds him and paints obscenities onto his body.

After graduating from university, Satoshi Takagi joined the advertising agency he had always dreamed of, and started his working life with great enthusiasm. Satoshi has a boyfriend who is more than a friend but less than a lover, but even when she tries to talk to him about the company, he only wants Satoshi's body and won't listen at all. “Am I just a body?” The distance between him and Satoshi has widened a little. Despite this, Satoshi did his best at work. He was actually starting to be attracted to his boss, Furukawa. However, Furukawa is a straight man who is dating Satoshi's colleague, an office lady. Although it is a dream that cannot come true after all, my feelings for Furukawa, who does his job in a cool manner, grows stronger every day.

Yuji is an engaged businessman, who decides to grope Asuka, a pretty young girl, on a busy Tokyo commuter train.

This film is another quality installment from the Chikan Densha Groper Train series – the longest running film series in the world. (Over 500 Groper Train films have been made!)
