A holiday in the families of Russia’s biggest oil oligarchs: their children, famous athletes of the world’s top level, are getting married. But at the very next international tennis tournament, the young husband—who had been stubbornly driving toward victory—unexpectedly and for no clear reason loses the match to the son of his own coach, an up-and-coming tennis star. What’s more, when the newlyweds return home, they die in a car accident. The prosecution closes the investigation because the perpetrators of the tragedy themselves are dead. And then the case is assigned to A. Turetsky and his team.
