Caged Women (1982)

Laura Gemser (of the EMANUELLE series) ostensibly reprises her Emanuelle persona in this exploitation classic. Here, Emanuelle is a reporter going undercover at a prison notorious for its brutal treatment of prisoners to expose its human rights violations for Amnesty International. Posing as Laura Candel, a prostitute, Emanuelle is incarcerated and is immediately shocked at not only the treatment of the prisoners, but also the borderline psychotic behavior of her inmates. Unfortunately, things get worse when Emanuelle's true identity is discovered by the prison warden, who subjects Emanuelle to the torture that she had come to discover.
