Two Hong Kong policewomen (Ida and Hon) take on a Japanese boss who has returned from a seven-year exile to retake his old turf.

Bullet, a female triad member, is recently released from prison. Bullet hooks up with her old gang rather quickly, although she is being closely watched by her policeman father and his gritty female partner Big Aunt . Bullet steals some jewels belonging to triad gangster Chin Bo while helping her friend May, who has been forced into prostitution. Chin Bo, also known as Brother Mad, kidnaps May and another of Bullet's friends to secure the return of his fortune, but the exchange goes wrong and a furious gun battle erupts.
