Former riot policeman and sniper Mikhail Karpov never managed to get out of the past, where he strangely ended up as a result of a car accident in 2018. He remembers with regret the Internet, mobile phones, Mercedes and Land Cruisers, and free movement throughout the planet. He misses his family, his wife. True, here, in 1971, in a country called the USSR, his young parents and his beloved grandfather live. But Mikhail does not yet dare to look at his relatives even from afar, because now he is older than his parents. He decides to devote all his strength and knowledge to the fight for the preservation of the Soviet Union. In addition, he considers it his duty to destroy all serial killers known to him, primarily those who attacked children. To implement such plans, significant funds are needed, but he has already learned how to make a living here - the novels of science fiction writer Mikhail Karpov sell in huge editions in the USSR.
