The film opens with a young Romanian woman, Elena, being driven to the home of her new employers, Danish couple Louise and Kasper. Louise and Kasper are a wealthy couple living in near-isolation in a lakehouse in the forest. Kasper explains that Elena was hired for some extra help because Louise has been weakened by recent surgery. The couple lives without electricity and lives off the food they grow, as well as eggs from the chicken coop they keep, and the only communication with the outside world is through a simple landline phone. Although Elena hears a few unusual noises at the house, she otherwise fits in easily.
