Valentin Milyutin, suspected of organizing the contract murder of his business partner, has been released from custody. But as soon as the businessman left the walls of the detention center, he had to return to the detectives office: his wife Polina was killed right on the threshold of their apartment. At first, the investigation suspects Milyutin's son Anatoly, but his father has long since deprived him of his inheritance and he has no motive. Suddenly, a new person appears in the case - Milyutin's comrade in prison, a certain Ledogor.
