Chained Heat (1983)

Linda Blair plays Carol, a young woman who must serve 18 months in prison after killing a man (by accident). The prison turns out to be brimming with decadence, corruption and sleaze, where the other female inmates are sadistic and the guards and warden are no better. Racial tensions are high as the inmates is divided into two factions who must either join together against the management or kill each other trying.
