In the 17th Century a group of nuns claimed to be possessed by the devil with Joan, the convent head, leading the possession stakes with at least 8 demons on her slate. An innocent young priest, the latest in a long line sent to investigate, is going to have to go to hell and back to save her soul. Chronologically the film acts as a sequel to Ken Russell's 1971 shocker 'The Devils', and if you've seen that you'll know what a lying bitch Joan is. Superb black and white photography gives an expressionist feel to this quality drama with some choice Judaeo-Christian theology thrown in.
