Caged Heat

"Caged Heat" (1974) is a women-in-prison film that follows Jacqueline Wilson as she is sentenced to 40 years in prison for possession of illegal drugs and attempted murder after escaping from an undercover operation. Upon her arrival at Connorville Correctional Institute for Women, Jacqueline befriends fellow inmates Belle Tyson and Pandora, who soon plot their revenge against the sadistic warden and corrupt doctor conducting illegal "therapeutic" experiments on the inmates. Led by Maggie, one of the inmates, and later joined by Jacqueline herself, they hatch a series of daring escape attempts, including hijacking a transport truck and taking down the prison's authorities in a shootout.
