 Nunsploitation, along with nazisploitation, is a subgenre that ran a parallel course alongside women in prison films in the 1970s and 1980s.As with prison films, they are set in isolated, fortress-like convents where the all-female population 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.
