Gang leader Nami (cult film legend Meiko Kaji) kills a member of a yakuza group and goes away to prison. Upon her release three years later, she’s a shamed woman confined to living in the shadowy world of sex clubs and street gangs. She returns to the city to live with her uncle, a billiard-hall owner, and after befriending pimp and ne’er-do-well Ryuji (Tsunehiko Watase), she gets a job working at a hostess club in the chic Ginza neighborhood, where the expensive shops and neon lights conceal a dark world of crime and sexual slavery. But when a rival gang attempts to muscle in on the club, Nami becomes enmeshed in a violent struggle that forces her to wield a skilled pool cue to defend her uncle’s business, and eventually a short sword to wreak bloody vengeance upon her enemies.

Reiko Oshida stars as a young wannabe gangster tough girl, just released from reform school. She tracks down one of her classmates fathers, who runs an auto repair shop that the local Yakuza are trying to force out of business and take over, and starts working for him. At the same time a recently released from prison, and now ill Yakuza is trying to make a new life for himself and his girl, a friend of Reiko's, who also just graduated from reform school. A fateful car crash brings the two on a collision course with each other and the brutal Yakuza clan, which can only end bloody vengeance.

Rika is released from girls detention school and then winds up at a lounge bar where she finds her other classmates working. This lounge bar is run by Junko Miyazono.
