Near a town in the Moscow region stands an old, half-ruined estate, where, they say, the ghost of the Mistress wanders. The Mistress can’t stand intruders on her territory—but Yulia and her friends didn’t know the legend of the estate, so they spent a fun evening there. Soon, one of her friends is found dead in that very estate. Yulia herself begins to feel a frightening presence nearby, and a new neighbor shows unexpected interest both in her and in the murder. Will she be able to sort out what’s going on before the Mistress of the old house comes for her?
