Reform schools are a way of protecting society by ridding it of lawless juvenile delinquents. But who's protecting the juvenile delinquents from corrupt reform schools? Rica could be considered a bit of an expert on reform schools, having spent most of her early life in and out of them. When Rica is dragged back once again, she gets a severe beating and is finally sent off to a mental hospital with the intention of selling her and her pals into a slave trade. A trader takes Rica's friend Jun to a mountain cottage where she's pegged for the lead in his clandestine porno film operation. Once again, it's up to tough-as-nails Rica to bust up this corrupt racket once and for all!

Ryoko leaves the chaos of her dorm for the peace and quiet of her own place because she wants to keep her relationship with a doctor at Murata Hospital a secret. Unfortunately, that privacy is short-lived as she discovers a “peeping tom” next door neighbor that spies on her all the time. When the doctor’s wife learns of the affair, poor Ryoko gets caught in a web of jilted lovers, frisky lesbians, slapstick sexual assault and embarrassing incidents with household appliances.

The relationship between a rich young student and his lower class friend changes when they start to live both at a guest house. Both will be attracted towards Iko, the beautiful daughter of their landlady.

First film of a trilogy following the dramatic life of Rika, a half-Japanese/half-American woman who becomes the tough-as-nails leader of an all-girl crime gang.
