A veteran of the criminal investigation department, a retired police colonel, having stood up for an unknown guy, gets stabbed - the second in his life. He received the first back in 1976, when he was a yellow-haired district police officer. Already an elderly man, he had the chance to end up in a hospital bed in the body of himself - a junior police lieutenant. And he will again have to become a district inspector in Pankino - a former village called Ubei-gorodok. Will he simply go with the flow of life or try to change the course of history?
