Guards Sergeant Alexander Mechnikov has completed his five-year contract and retired. He is free, has the means to live, wants to get married and live like an ordinary man. However, his native state and his former commander Colonel Yeryomenko have certain plans for him. And the retired sergeant becomes an officer in the long-range reconnaissance department of the State Security of the Kuban Confederation and commander of his own detachment. New adventures and journeys through a world devastated by plague await Mechnikov. Before him and his comrades lie the Kuban and the Don, Ukraine and Kalmykia, Turkey and Stavropol Krai. Everywhere there is danger and the unknown. The State Security fighters lose comrades, but despite the difficulties and numerous enemies, among them bandits, Satanists, and separatists, Mechnikov’s detachment carries out its orders and tries to survive.
