Young wife Sakiko is arrested for the murder of her husband. Despite her claim of innocence, that claim is not heard. Sakiko escapes and chases the real criminal who killed her husband. Her only clue is a sight of a tattoo on the murderers back. Sakiko hides in the city at night to find the real culprit. Offering her body to see the back of the men she seeks out, Sakiko must uncover the truth to the murder of her husband before it is too late.

Taneno, an elite police officer who became obsessed with righteousness, attacks his wife, Mitsuko, with a goya (bitter melon) for pleasuring herself with it. As he leaves prison after serving his sentence, he accidentally boards a taxi offering illegal prostitution services. On board, he meets Omitsu, a woman who looks just like Mitsuko. His presence in the car sends her away from the taxi. The driver holds Taneno responsible and forces him to serve his taxi. Back in the force, Onari, a lazy cop, and Asadachi, a new recruit, begin their investigation on a suspicious taxi.
