Yūko is a newly appointed female public prosecutor. The first case she was assigned was a rape case. The victim was Shizuka Watanabe, 25 years old, whose occupation is a model; it was an incident that occurred while she was returning home late at night. Next, an office worker, Akiyo Machida, 22 years old, was also subjected to the same method of assault. Yūko, who works on the investigation with the cooperation of her superior, who is also her lover, faces a difficult situation when both victims withdraw their complaints.
