Joshû sasori: Dai-41 zakkyo-bô

Nami Matsushima (Meiko Kaji) is being kept bound in an underground solitary confinement cell, where she fashions a shiv out of a spoon by holding it in her mouth and grinding it against the concrete floor. The prison's chief warden, Goda, is to be promoted to a higher post shortly. When an inspector visits the prison, Matsushima is brought out of confinement for one day. During the inspection, Matsushima attacks Goda and slices his face. The other prisoners start to riot, but it is quelled by the guards. Believing that Matsushima may inspire the other prisoners to revolt, Goda assigns four guards to publicly rape her. Matsushima strangles and kills one guard, and Oba and the other prisoners capture the other guard and blow up the van. When Goda sees the wreckage, he sends search parties after Matsushima. The prisoners escape to an abandoned hut near a village, where they decide to wait for nightfall and steal new clothes to escape in. Oba reveals her crime: when she found her husband cheating on her, she drowned her two-year-old son and killed her unborn baby by stabbing herself in the stomach. In the village, the prisoners find a mysterious old woman wielding a dagger. A surreal sequence follows in which a narrator reveals the crimes for which each prisoner was jailed. Oikawa sneaks out of the hut and into her nearby family home, where she is reunited with her son, but finds two prison guards waiting for her. Matsushima kills the guard following Oikawa. During the scuffle, Azama is shot in the stomach accidentally and dies shortly afterward. The prisoners, led by Matsushima, take revenge on society, torturing and killing those who have wronged them. As the bus approaches a checkpoint, Oba throws Matsushima out of the bus to serve as a decoy. Matsushima is captured, but Goda's men arrange a roadblock in front of the bus. Oba orders the prisoners to kill the hostages. She kills the bus driver and commandeers the bus, scattering the guards and escaping the roadblock. By nightfall, the bus is surrounded by the police. Goda sends Matsushima to the prisoners to learn the hostages' status. Matsushima lies and says the hostages have been killed, and the police lead a charge on the bus. The prisoners push the three rapists off the bus, where they are killed in a hail of police bullets. In the ensuing fight, all the prisoners except Oba die. Oba is injured and set to return to prison in the same vehicle as Matsushima. Goda orders the guards to stage an escape attempt by Matsushima in order to kill her. The guards stop at a junkyard and are about to shoot her when Oba saves her by biting the guard on the neck. Matsushima kills the guards. The next morning, as they flee through a junkyard, Oba succumbs to her wounds and dies. Matsushima tracks down Goda to Tokyo and stabs him to death. The film ends with a fantasy sequence in which all the female prisoners of the jailhouse, wearing their striped prison dresses, run free through the city, passing Matsushima's knife from woman to woman.
