After answering a vacancy, Antonina gets a job as a caretaker at the mansion of a young owner of a chain of jewelry stores. Her task is to look after his twin sister Evgeniya, who was seriously injured after an accident on a climbing wall. However, very quickly Antonina notices: it seems that Evgeniya’s caretaker help is needed the least of all. Something is going wrong in the house— the air seems saturated with a threat, and strange, unexplained events occur around her. It feels like even the walls are watching her… or like the gaze is coming from an old portrait on the wall.
