Nikolai Vorontsov, sergeant of the Russian army, yes, a special forces soldier, returning from another business trip, received a strong electric shock and ended up in the body of a private of the Russian Imperial Army. In the middle of the battle, in a dirty trench, our contemporary quickly came to his senses, because he had been taught to serve his homeland all his life. Denikin's Iron Brigade is a serious test. How long can Nikolai last without running away, without getting out "upstairs" to the tsar, in this terrible time? But there is an even more terrible event ahead - a revolution!
