Caged Women (1991)

Beautiful young American tourist Janet Cooper goes on vacation to a remote South American country. After being arrested by a corrupt cop and subsequently found guilty of a trumped-up charge involving possession of narcotics, Janet finds herself incarcerated at an isolated castle located deep in the jungle that serves as a hellish women's penitentiary. The brutal staff at said prison not only treat the inmates as their own sexual playthings, but also force the ladies into prostitution and even let decadent rich folks hunt them down like animals in the wild.
