A secret organization of hired killers, called the Killer Club, receives an order to eliminate a number of government officials of the highest rank. Opposing the daring plans of the killers are professional counterintelligence officers - “gunfighters” Matvey Sobolev and Vasily Baluev, who are fluent in all types of hand-to-hand combat. It is they who will have to fight tooth and nail not only with killers, but also with the mysterious Union of Nine Unknowns, which is essentially the “shadow government of Russia.”
