La Settima Donna on AllMovie

This shameless knockoff of Last House on the Left even goes so far as to repeat the detail of having the theme song performed by the lead villain. Florinda Bolkan (Non Si Sevizia un Paperino) plays a nun who takes the teenage girls in her care to a remote house where they rehearse A Midsummer Night's Dream. Ray Lovelock and a pair of thugs show up, brutally raping and terrorizing the girls -- killing one by raping her with a cane -- until Bolkan renounces her teachings and seeks bloody revenge. Utter nonsense, but AC/DC and Roxy Music are on the soundtrack, so it isn't a complete waste. Director Franco Prosperi is best known for co-directing Mondo Cane and Africa Addio. Sherry Buchanan (Dr. Butcher, M.D.) co-stars with Laura Trotter.
