Nunsploitation, along with Nazisploitation, is a subgenre that ran a parallel course alongside Women in prison films in the Seventies and Eighties. As with prison films, they are set in isolated, fortress-like convents where the sexually repressed all-female population inevitably turns to lesbianism and perversity. The element of religious guilt allows for lurid depictions of “mortifying the flesh” such as self-flagellation and painful, masochistic rituals. The Mother Superior is usually a cruel and corrupt warden-like martinet who enforces strict discipline (more opportunities for whippings and medieval-style punishments) and often lusts after her female charges. An equally sadistic and lecherous priest is often included to add an element of masculine menace to the story.
