A small time crook who sells rabbits for a living frequently gets himself into trouble with loan sharks and the yakuza. He dreams of becoming a successful big-shot and embarks on the life of a yakuza hitman.

Girl Boss Ruriko and her cellmates escape from a greedy corrupt reform school that's more interested in cheating the government out of money than reformation. Each having their own reasons for escaping, they go their separate ways. With the help of a young mechanic, who's also on the lam, Ruriko tries to realize her dream of leaving the island of Japan behind. But the authorities are always one step behind her...

In the 1970s, the Japanese youth emancipation also found its way into the yakuza (crime) societies. A Girl Boss may have a choice between bikes, and between boyfriends. But she has to defend her choices the hard way, as her triumph and power over the girls' gang is questioned by her female rivals, and the all powerful Yakuza Boss. She inspires loyalty to her girls, and to men to the extent of many of them literally giving their lives for her - in a world of knife and gun fighting, bike and car chasing, and violent death.

When two Girl Bosses fight each other over territory, their enmity is difficult to solve - they are equals in looks, strength, determination, and power of their respective girl gangs. So, the way is open to a mischievous Yakuza Boss who invites them for a peaceful way to decide their feud: a sexual challenge for him to decide who is the better Girl Boss. Trapped, both are subject to the man's lust and sadistic assaults. They escape by joining forces against the yakuza gang, though it costs one of the young women her life - when she was friends already with her former enemy.

Natsuko is so good at using that super-strong vagina of hers that she can fuck guys to death. In the end, she’s pitted against a sexual superman and a showdown ensues. There’s also a subplot about a mad scientist type who needs vaginal juices to create a potion designed to turn Japanese girls black.

The Kanto Gypsies, a tough girl gang, hide out from the law in the middle of a disputed gang territory, where they end up getting kidnapped by sinister underworld thugs. After breaking free, the girls set their sights on one thing: revenge. Miki Sugimoto stars as girl boss Komasa, the ruthless and sadistic leader of the Kanto Gypsies who possesses more than enough brains to match her killer looks.

Reiko Ike stars as the daughter of a man who has been pushed into drug dealing by the local Yakuza mob. Having outlived his usefulness to the gang he is murdered and Reiko is gang raped, leading her to attempt a knife attack on the Yakuza boss (Ryoji Hayama) at a swank nightclub. Failing to kill him she ends up in prison, where she befriends a crew of other malcontents (including Yumiko Katayama and Chiyoko Kazama) and meets the Yakuza boss's girlfriend (Miki Sugimoto). Upon release Reiko reassembles her mob and launches a Machiavellian scheme to engineer a gang war between Hayama's Oba Industries and the formerly dominant Hamayasu Clan. The rival gangs begin killing each other off and Reiko works her way closer to her ultimate vengeance.

Many persons visit the hot springs resort to try out Reiko's famous vagina with quivering walls, "the sensation of worms wiggling about"... that won her her nickname (Mimizu = earthworm).
