A famous television journalist, Leonid Kondrashin, was kidnapped in the North Caucasus. They demand a ransom for it - a collection of precious stones that the oligarch Chegodaev, the owner of the TV channel where the journalist worked, gave his young wife as a wedding gift. The thieves have a demand: the jewelry must be handed over to them by one unarmed person - private detective Denis Gryaznoe. The Russian authorities and intelligence services are completely bewildered: firstly, they have no idea who he is, secondly, why was he chosen, and thirdly, where can they find him?
