Emanuelle, a reporter, comes just a little too close to exposing a corrupt official, and is sent to prison on trumped-up charges. In the prison, the inmates are constantly humiliated and tortured by the prison staff. Overly affectionate prisoners are forced underwater, while others are obliged to look on. Emanuelle finds an enemy in the deranged Albina, who "runs the prison." For the pleasure of the warden, Emanuelle and Albina are forced to fight each other with knives. Bad becomes worse when four men awaiting execution escape and take over the prison. Gore flows like water.

Investigative reporter Emanuelle (Laura Gemser) finds herself locked up in a women’s penitentiary run by a ruthless warden and her brutally sadistic guards. Vowing to exact revenge upon the corrupt politician who set her up, Emanuelle must first survive the daily torture and attempts at her life by grotesque prison bully Albina. Into this powder keg of smoldering sex and violence comes four bloodthirsty death row inmates led by "Crazy Boy" Henderson (Gabriele Tinti). Blasting their way to a prison takeover, this quartet of psychotic criminals takes advantage of the all-female situation only to find they have bitten off more than they can chew. With the police launching an all-out assault upon the rampaging prisoners, Emanuelle battles to stay alive amidst the bloodshed and depravity...and the most horrifying game of Russian Roulette ever seen!

All hell’s breaking loose in the most gruesome women-behind bars film ever made. Womens Prison Massacre is renowned Italian exploitation maestro Bruno Mattei’s bloody sequel to his 1982 cult classic Caged Women. Also known as Emanuelle Escapes from Hell and Blade Violent.
