CEO of a large company Platonov is forced to retire. Events were accelerated somewhat by a memo written by one of the candidates for his post, Oleg Sergeev. During a corporate party, Platonov's assistant Nikolai did not hide his worries about the future state of his affairs - Sergeyev dislikes him, which clearly threatens to be fired. Platonov made it clear to his subordinate that he was washing his hands, and after a while Sergeev was found dead in the parking lot.

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.
