Santa Fiora convent, 19th-century Italy. Sister Angela, the Mother Superior, welcomes seemingly innocent orphaned Isabella to protect her from unscrupulous Uncle Don Ascanio. And before long, the shameless exhibitionist novice shows her true colours. Then, as if that weren't enough, the unexpected arrival of wounded Lieutenant Guido stirs up trouble, and a sexual rebellion brews over. Is the handsome stranger the Devil incarnate?—Nick Riganas
Gripped by sexual desire, nuns pleasure themselves and each other in fear of the Mother Superior. One night, a wounded man is found on the grounds, and becomes connected to a mysterious pagan statue on the premises.
