Class Trip is a 1998 French film. Its original French title is La Classe de neige, which is the name given to class trips in the snow. It tells the story of a young boy on a school skiing trip who suffers anxiety attacks that bring on disturbing nightmares.
He is befriended by Hodkann, another pupil. One of Nicolas main fears is wetting his bed, and the situation gets worse when he gets a bed just above Hodkann. At night Nicolas tries to stay awake but falls asleep, waking up from a wet dream but believing he has wet his pants. He leaves his bed to clean his clothes and while returning he discovers it snowing outside. Nicolas goes outside into the freezing cold and ends up locked out, and in desperation curls up inside the car of his ski instructor, Patrick. Before he drifts off to sleep he sees a van driving away. He is found in the morning by Patrick and is taken in to a study with a fever.Later that day he goes to a caf while the other boys are skiing. While in the caf, police come looking for Ren, a young boy who is missing. That night while sleeping he has a nightmare. He dreams that he is at a theme park with Hodkann and Patrick and that he goes on a giant caterpillar while his little brother is looked after by another seemingly friendly man. Once he is on the caterpillar he sees his brother being walked to a white van by the stranger. Later he is found outside the park after having one of his organs taken. The dream is poignant because Nicolas, months before, had not been allowed to go on a similar ride because it would have meant leaving one of the brothers with a stranger. After declining the strangers offer to watch the brother, Nicolas father warns against stranger danger, claiming this includes a risk of organ theft. At the end of the story Nicolas finds that his father was not in an accident as he had day dreamed, but rather that his father was a monster and possibly abused children. Although it is never explained why the father has been arrested. ........
