The second in a series of exploitation films based on a Japanese adult manga magazine, this over-the-top jailbreak movie pits the silent-but-deadly Scorpion (Meiko Kaji) against a sadistic warden and other adversaries. As the film begins, Scorpion is shackled in an underground solitary confinement cell. She sharpens a spoon, which she holds in her mouth, by scraping it repeatedly against the damp, dirty floor. Then the warden has her dragged to the yard to present a positive image of the prison to a visiting dignitary. Scorpion seizes this opportunity to attack the warden and incite a riot. The warden punishes the women by placing them on a tough work detail and instructs four guards to rape Scorpion. His plan to turn the women against her appears to be working when several inmates assault Scorpion while they are being transported in a van; but when the guards check the van, they are overtaken by Scorpion and the other women. As they flee from the law, the escapees find a village that's nearly buried in volcanic ash; a mysterious old woman with a knife who reveals their backstories; and a tour bus with rapists who kill one of the women. The women hijack the bus, but the police continue to pursue them and force a showdown.
