Greta is in charge of Los Palomas, a mental hospital located in South America, exclusively for women suffering from "sexual deviances".
A girl named Abbie (Tania Busseller) goes undercover as a patient to find out what happened to her sister Rosa. She is soon stripped and hosed down and given a uniform. Abbie soon meets Juana (Lina Romay) who is the lead bad girl inmate, and pet of Greta. Juana has more freedom than others in the facility.
It is learned that the doctors use the patients for a series of black market porn films. Greta uses a syringe to inject a shot of acid into Abbie's vagina. She then uses a plastic bag to choke the life out of another inmate.
In the end, the patients uprise and capture Greta. They pin her down on a bed and begin ripping her flesh with their bare hands and teeth. We see and hear lions doing the job the inmates partake in, and it is obvious that Greta is devoured.
