At night, a terrible event occurs in the psycho-neurological department for adolescents - one of the patients almost dies. Doctors fear that history will repeat itself and end in tragedy. There is a version that teenagers play "dog buzz", a game of suffocation at night. Ivan Khristoforov, a talented psychiatrist who treats his young patients not so much with pills as with pedagogical methods, must figure everything out and stop the deadly game. (imdb)
