The B-grade genres of sexploitation, blaxploitation, and jailhouse flicks mixed with this grotesque sex- and violence-filled melodrama. Linda Blair stars as Carol Henderson, a naïve and inexperienced teenager who is sentenced to 18 months in a women's prison after accidentally killing a man. Once she arrives, Carol meets sadistic, perverted Warden Bacman (John Vernon), who keeps a hot tub in his office. She also encounters the two top-dog prisoners, Ericka (Sybil Danning) and Duchess (Tamara Dobson), who are at war with each other, the leaders of factions in the facility's simmering racial tensions. Then there are the drug-dealing lesbian rapists and the prostitutes, who answer to the warden's snugly-outfitted assistant, Captain Taylor (Stella Stevens). In the meantime, Taylor's lover is secretly carrying on an affair with Ericka. It's a cauldron of fear and rage, but when the prison's corrupt management goes too far, race considerations are set aside as black and white convicts band together.
