This man's life would have ended in the twenty-first century, but something went wrong, and he ended up in 1940, in the body of seventeen-year-old Kostya Zvyagintsev. The main character is a former mercenary, an Afghan warrior who had only two principles in his life: not to betray his homeland not to fight against his own. Another time turned out to be a stranger for him, because he did not fit the standard version of a citizen of the Land of Soviets, and he had to look for his place in this new life. And he also had to survive, as once in the mountains of Afghanistan or in the rainforests of the "banana republics," after all, war came and he could not change the oath and began to defend his homeland... Sergei Boguslavsky is not only trying to find his place in a new world for himself, but he is also doing everything to prevent a coup and the ensuing civil war, which plunged Russia into chaos. Having created a new punitive body on the basis of the gendarmerie, he will destroy the opposition in the country, prevent a number of attempts on the sovereign, make the people believe that there are no more untouchables for Russian justice.
