Transcaucasia. Autumn 1808.
The Russian army under General Field Marshal Gudovich prepares to storm the formidable Erivan fortress. Among its ranks is Timofey, a student from the 21st century who ended up here at this time by the will of fate. After passing through dozens of clashes and battles, he is now a junior officer of the Narva Dragoon Regiment, and it is he who must lead his men up the walls of this terrible stronghold.
"Squadron—dismount! Form up into the assault column! Put bayonets on the rifles!"
