Considered a classic of Norwegian cinema Kåre Bergstrom adapts Andre Bjerke's novel about a group of friends (author Bernhard, his wife Sonja, psychoanalyst Kai, magazine editor Gabriel, lawyer Harald Gran and his fiancée Liljan) who venture into the Osterdal forests to join Liljan's brother Bjorn at his remote cabin. Liljan's suspicion that her brother is in danger are confirmed when they arrive to find his dog dead and no sign of him. The gang is spooked further by a legend associated with the cabin: that a man who lived there once killed his sister and her lover and then drowned himself in the lake. Since then, it is said that anyone who stays in the cabin will be driven to the same fate.
