It's about a small family buying an old house, were they find out they are not alone.

A small family moves from Oslo to the small village, Nerås. This is where the parents hale from, while the daughter was born in Oslo. They wanted to live in more peaceful surroundings because the daughter have Asperger's, so they bought an old house on a farm called "Killungard". It turns out they are not alone in the house, and unpleasant things start to happen.—Magne Steinsvoll
