In order to protect detective Bednyakov from major troubles, General Gryaznov, head of the Moscow Criminal Investigation Department, arranged for him to be transferred to another job, to a quiet place. But there, “as a result of an accident,” Bednyakov dies. Gryaznov is convinced that this is not an accident, but he has no evidence, and the official investigation has already been closed. The head of the MUR has no choice but to ask a private detective, his nephew Denis Gryaznov, to look into this.
