 The traditional Hellestad Boarding School is celebrating its centenary, and the students are planning a big party. However, there is a dark legend about a brutal murder of three students by a local farm a hundred years ago. The killer drowned in a lake nearby and his body has been not found. One year ago, the disturbed intern Rebecka (Sasa Bjurling) committed suicide during the anniversary speech of the arrogant dean, and her deranged father escaped from the mental institution where he was lodged. The student Sara (Rebecka Hense) is preparing a composition about the tragic legend, and finds new evidences compromising the name of a traditional local family and top contributor of Hellestad. Meanwhile, two new arrivals, Leo (Peter Eggers) and Felix (Jesper Salén), become close to Sara and her roommate Therese (Jenny Ulving), and students and staffs are vanishing in the place.
