The Russo-Japanese War is in full swing. The Japanese Empire begins the annexation of Sakhalin. To protect the island, a militia is formed from convicts. Alexander Lyubich, the captain-captain of a separate border guard corps, who, by the will of fate, ended up in hard labor, without hesitation, joins the squad, but in the very first battle he is captured. It would seem that everything is predetermined, death is inevitable, but a series of incredible events allows one to avoid execution, and then Alexander begins to understand that he is no longer the same person as he used to think of himself: the former captain-captain was possessed in a completely incomprehensible way by a cruel medieval warrior, Count, by the grace of God, Jean VI Armagnac. How this could happen is still unknown, but this is not at all a reason to refuse to defend the homeland. Annexation, you say? Well, well...
