The corpse of a man is found in a dark alley in a small Siberian town. The murder was committed with particular cruelty, but otherwise this crime seems quite ordinary. However, when examining the body, the forensic expert discovers amazing things - the terrible wounds of the deceased man healed with amazing speed, the victim only had a few minutes to survive. This is only the first mystery on the path of the young investigator of the prosecutor's office. Then a completely stunning secret is revealed: in the midst of a fierce confrontation between mysterious creatures, which people have called “archangels” since ancient times. Grassator, Exucator, Croesus - the names of the archangels cut the ear like a knife cuts paper. Archangels are not familiar with human feelings. They easily play with the lives of mortals; they involve the entire Earth, all countries and continents in their battle. The confrontation threatens to change human civilization forever... unless we manage to awaken at least something human in one of the archangels.
