But at the next international tennis tournament, the young husband, stubbornly striving for victory, unexpectedly and for unknown reasons loses the match to the son of his own coach, a rising tennis star. And what’s more, when returning home, the newlyweds die in a car accident. The prosecutor’s office stops the investigation due to the death of the perpetrators of the tragedy. And then the case is entrusted to A. Turetsky and his team.
