In Tarasovka, a young man, Maksim Gorokhov, is murdered. Marakuyev suspects Maks’s brother, Sasha, who has disappeared, of the murder... But Olesya disagrees: she has discovered that strange things had been happening around Maks and Sasha lately. And, in Olesya’s opinion, Sasha did not run away, as Marakuyev believes, but is himself now in danger... As usual, Olesya turns out to be right. She finds Sasha and saves him from death by identifying the real killer.
