Making enemies with the security officers in 1937 was like signing your own death warrant. And Leningrad student Yaroslav Korsak managed to become a personal enemy of the city’s security officers. We need to go to the bottom, change documents, start a new life. Yaroslav managed to “reincarnate” in such a way that he was eventually enrolled in the top-secret sabotage group “Sterkh”, which carries out lightning-fast operations anywhere in the world. He became one of the best fighters in the group, but the past, like the clockwork of a bomb, inexorably ticks behind the back of the fearless saboteur.
