Plot

Four female convicts escape from prison and take a bus full of young female athletes hostage, and take refuge in a judge's house. Soon enough, the police surrounds the place, but the escapees are not giving up without a fight.

Four female convicts break out of prison, and during their escape they take hostage a bus full of young female tennis players. They drive the bus to the house of the judge who originally sent them to prison, where--since this is after all a women-in-prison picture--the hostages undergo various forms of physical and sexual abuse in various degrees of nudity.—frankfob2@yahoo.com

A blue bus loads a number of college girls from a coffee shop in the snowy meandering mountain road - tennis players (ARTEMIA TERENZIANI, ANGELA DORIA), the black champion Terry (INES PELLEGRINI), and Claudine, a girl who has first aid training (MARINA D'AUNIA).

About the same time, four women convicts are escaping from Portobello Penitentiary: Monika Apler (LILLI CARATTI), a 25 yer-old terrorist; Ursula (ZORA KEROVA aka ZORA KEER); a hefty 25 year-old serving time for robbery with violence; Diana Brandley (DIRCE FUNARI), a hustler serving time for blackmail and murder; and Erika (ADA POMETTI), a lesbian drug addict and smuggler. They run through a green valley, but are intercepted by the criminal police. In the shoot-out, Monica and Pierre, the terrorist who helped the girls out, kill the two policemen. Pierre is wounded. They take the white police car and drive up the mountain. They overtake the blue bus, and then force it off the road. Then, they go on board, and hijack the bus.

Pierre is attended to his wound by Claudine. Willy, the bus driver (FRANCO FERRER) tries to jump Monika and take hold of her gun, but she beats him back, and menaces to shoot him, keeping him quiet.

Monika directs the bus to near a mountain villa, twelve rooms. She knows it belongs to a judge (FILIPPO DE GARA), who is the father of Terry's girlfriend. Monika takes Terry with her, and comes to the house. Terry seems to recognize the judge, but not vice-verse. The middle-aged, spectacle'd magistrate serves the two girls sandwiches, then he hears a radio announcement giving the identity of the four escaped convicts.

The convict girls hold the college girls hostage in the mansion. In a flash-back, one knows the judge has raped a young woman. Hefty takes Pierre away away from the lounge, as they await the coming of a Female Warden who tries to talk them to surrender. Ursula recalls how that bad woman searched for her day and night, and now she can take revenge... Erika calls the warden 'bull-dyke', and shoots her, out of lesbian love for Ursula. Of course, the police has the house surrounded, and used the parliamentary as a distraction to enter the house. Only, Diana sees a Policeman coming down from the roof, and they exchange gun shots; the girl is wounded in her lower right leg, but another cop dies.

Monika distributes free whisk from the judge's cupboard, and discusses politics with the Nurse. The Nurse throws away her drink, to try to keep sober for the expected hard time ahead, but Monika sees the girl's gesture. Erika confiscates the bottle from Monika, who is already under the influence. Asked by Nurse what she intends to do, Monika answers: "Right now I can think only of two things. One is to smash your face. The other is too personal."

Everybody is expecting a final assault by the police. Diana decides to take Claudine - the Nurse, in white leggings and hot pants - up to a bedroom, and make love to her, while there's still time. Ursula talks with Erika, and recalls how she was afraid of not having enough food to eat, then decides to go to the kitchen for a snack. Diana keeps drinking, and makes love to Claudine on the bed. Downstairs, Willy and the college girls are dancing around Terry - as if they were actually hosts, and not hostages of Monika and the other criminal girls. The judge is alone, having yet a nightmare with Monika's crotch - was she the girl he raped?

Claudine must have escaped Diana after her exertions, and hides behind the couch where Monika sits. Then, Monika goes to the kitchen, has some words with Ursula, and they engage in a shoot-out, and Ursula falls dead.

Meanwhile, Claudine attacks Erika, and the two women fight over a kitchen knife. One of them dies, with the big knife cutting through her belly.

Diana jumps out of bed, nude as she was when she laid with Monika, and walks away through the corridor. Monika calls after her from the bedroom door, and when she looks back at her, she shoots her dead point blank.

The criminal police police surrounds the house. Monika is sobbing by Diana's body, when Terry comes to her, and offers her to go with her in the escape car the police finally left in front of the door. The two girls drive off - only to be machine-gunned to death by the police ambushed beyond the next road bend.
