L'ÉNIGME BLANCHE (1985)

Like every year, five old friends come together in a chalet in the middle of a Canadian snow desert. Henri, his wife Apolline, brother-in-law Maxence, Jean and Paul are waiting for cozy evenings with board games and good food - a typical ski holiday. But on the first day Henri announces that he knows about the affair between Apolline and Jean. An oppressive mood spreads in the secluded hut until the spiral of jealousy and sadism kills one from its midst.
