Moscow, 1916. To escape the Tsarist police, the young Alexandre accepts a job as a doctor in the back of beyond in the Urals. The man he is replacing there was violently assassinated. By the wolves? Or worse? However, it is not the first time that the snow has been bloodied. With each new storm, death strikes those who are lost. Far from the communist revolution, Alexandre's mission turns into a violent thriller. Somewhere between an initiatory quest and a murder inquiry, between the modernity of the coming century and the obscurity of the Middle Ages, the Muscovite has to find a place for himself among the suspicious and superstitious peasants. At the risk of his life or his reason.
