Все самое лучшее (All the Best)

The ten-year-old adopted son of the famous singer Elza Parshina Misha dies under the wheels of a car. Misha's governess and Irina's producer unanimously blame the boy's death on his computer science teacher Sergei Byazirev, who allegedly attempted to sexually harass Misha. The investigation finds Byazirev, who makes a shocking confession that he is Misha's father and has been looking for his son for many years. The expert examination confirms Byazirev's words, and all suspicions are removed from him. Investigating the circumstances of Byazirev's visits to the Parshin's house, Bobrova meets Misha's sister Masha and notices the girl's traces of physical trauma. Bobrova believes that Masha's parents severely punish, however, a conversation with the girl's teachers convinces her otherwise.
