After thirteen years away, Nami (Meiko Kaji) returns to Tokyo determined to track down the man responsible for her father’s murder. En route, she intervenes to rescue a young woman, Hanae, whose own father has sold her into prostitution. This act of compassion draws Nami into conflict with a powerful Yakuza syndicate that considers Hanae its property and is intent on maintaining its grip over the Ginza district. With the aid of Ryuji (Sonny Chiba), Nami must confront both her long-sought target and the escalating threat posed by the criminal underworld.
