Police officers arrive at Natasha's home. According to witness statements, she was seen in the company of the missing Vadik. Yulya seeks professional advice from her husband, prison doctor Petya. He turns to the incarcerated Doctor for help, and the doctor's advice proves useful. Katya has a fight with her mother-in-law and leaves home. Petya picks up his son from a classmate's house and meets the boy's mother. Kostya has a private conversation with the Professor and records it on a dictaphone. An idea begins to form for the executioner: the father of one of the victims has approached him and Sasha with a request to kill the maniac. The $500 offer is tempting, but Kostya is convinced they can make far more money inside the prison.
