Synopsis:
The greatest film that Alfred Hitchcock never made, Henri-Georges Clouzot's Diabolique is set in a provincial boarding school run by headmaster Michel Delasalle (Paul Meurisse). A ruthless lothario, he becomes the target of a murder plot concocted by his long-suffering invalid wife Christina (Vera Clouzot, the director's own spouse) and his latest mistress, an icy teacher played by Simone Signoret
