In an old manor in Dubrovitsy near Moscow, birds are singing, centuries-old linden trees are rustling their leaves, a river is babbling and... a ghost is walking around. In the palace, whose owners were the Golitsyns, the Potemkins, the Dmitrievs-Mamonovs, and even Catherine II herself, the night watchmen quit one after another after spending one or two nights in this historical building. Art critic Anna, ghost hunter Anatoly and special services major Andrey go to the estate in search of truth. Will they be able to become one team and figure out: is there really a ghost or someone staged a clever falsification? And did they all come to the estate for the same purpose?
