Four teens go to a cabin in the woods, except there is no cabin. They camp out at the infamous Lake Bodom the site where four teens were murdered in 1960. They never caught the killer. Atte (Santeri Helinheimo Mäntylä) is on the nerdy side and has a theory about the killer he wants to test. His friend Elias (MikaelGabriel) likes girls, especially the damaged Ida Mary (Nelly Hirst-Gee) who had a terrible thing happen to her...details later. And her friend and lover (?) Nora (Mimosa Willamo) round out our foursome. Elias drives a Volvo station wagon, a chick magnet in Finland.
Yes, people die. Ida is set up early as the final girl as her dad "treats her like a dog" because of that thing. The film takes a nice wicked twist, and then changes directions into the film you thought it was going to be all along. It was like they wanted to make 2 different films.
