Two sisters are raped on the morning commute on their way to school on the subway, in full view of the passengers, by a bunch of chinpira. One sister commits suicide, so the other quits school and picks up a yakuza boy friend who teaches her how to shoot. The boyfriend is killed by his old gang and the girl becomes a cab driver hunting the chinpira who raped her and her sister. Along the way, she dispatches various yakuzas and rapists with her 45.
Wataru and his older sister keep moving from place to place because strangers have been trying to kidnap Wataru. After a previous private tutor/bodyguard proves incompetent, they hire a swimming instructor who happens to be in dire need of some extra cash...
Wataru and Makoto are two singers and on their way from a performance to an interview when they are ambushed. Their attackers, who identify themselves as the "Noblemen Squad" take Makoto hostage and leave Wataru and their female manager behind. Luckily, the manager's brother (Ren Osugi, here working under the pseudonym Kyoji Saeki) drops by and starts training Wataru so he can rescue his partner.
