Skuggornas hus

Teacher's Henrik and Gia work at the same school. It's been two years since Maria Wagner, the lady who founded the school, died in an accident. To pay tribute to her, they decide to take the students to Gotland - the island where Maria Wagner grew up. The second purpose with the school trip is to learn the kids about the islands history. While staying at Gotland, they're going to live in an old house called Pemba. Soon mysterious things starts happening in and around the house. Are they really alone in the house?
