Young Katya meets a merry band who have a particular way of entertaining themselves: they organize parties in unoccupied houses. And Katia knows an ideal place: at the water's edge, an old dacha whose owner has long since left. An isolated house in which at the beginning of the last century there was a living room of spiritualism. The state of abandonment of this distressing and even frightening place worries no one... In the middle of the evening appears the one Katia had not expected to see: the mysterious master of the place... A man whom she loved. A man in the grip of the forces of the other world.
