Marie, a successful businesswoman, really, really wants to be a good person but she always seems to have more than her fair share of rivals and enemies. Conveniently for her, such individuals frequently meet with accidents that usually prove fatal. Perhaps her good fortune has something to do with the special hot chocolate she makes for them. Based on a novel by Charlotte Armstrong, Nightcap was directed by Claude Chabrol, stars Isabelle Huppert, and has an 84 percent rating at Rotten Tomatoes.
