With great difficulty, having fought off the persecution of Satanists, Krylov returns to the city of Troitsk, where his adventures began. However, there he awaits arrest and an indefinitely long imprisonment on false charges. To get rid of the “werewolf” policeman, he again uses the “time machine”, trying to return to his time, but instead ends up in our recent revolutionary past. There he is met by stern commissars in leather jackets and legendary heroes of the revolution, selflessly devoted to the new ideals of communism.
