A woman murders her boyfriends and steals some diamonds he has smuggled. She gets found out though, and locked in a prison with an evil sadistic lesbian warden. She immediately sets about planning her escape with some of her fellow inmates, but the plans are even more difficult than they seemed when set in motion.
Unfortunately the movie Hell Behind the Bars is not yet available on HBO Max.
