A lushly filmed exploration of the relationship between flesh and spirit from Polish provocateur Walerian Borowczyk, director of Blanche, The Beast, and Immoral Tales. Behind the walls of an apparently serene convent, a zealous abbess tries in vain to keep order and prevent her sexually repressed charges from experiencing the sins of the flesh. When the unfortunate young nuns get out of control, the church inflicts cruel punishment for their carnal crimes. Erotic, colourful and highly charged, Behind Convent Walls features striking handheld cinematography by Luciano Tovoli (Suspiria) and the final performance of Borowczyk's wife, Ligia Branice.
