The film portrays a desolate St. Petersburg, with peeling windows in ancient, sparsely inhabited buildings, and empty trams traveling aimlessly through deserted streets. Wandering alone through this bleak landscape is an unnamed man with no memory, no past, and no friends. The rare individuals he encounters address him differently—some call him Sergey Sergeyevich, others Peter. A delicate blonde woman he meets at a snow-covered cemetery calls him Boris and claims to be expecting his child. Each person he meets demands something from him, but his only desire is to find a room where he can live, however, even this modest goal proves to be unattainable.
