Aleksandr Turetsky, who almost died from an explosion in an orphanage, lies in the hospital, but is eager for action. He invites his boss, Deputy Prosecutor General Merkulov, to find the former “soldier of fortune” Pletnev, who fought in Angola, who can tell the origin and meaning of the amulet found on Turetsky’s jacket after the explosion. Turetsky’s wife helps Merkulov with this. Pletnev is unofficially included in the investigation, but suddenly Merkulov is removed from the case: it turns out that he brought a “werewolf in uniform” into the investigation.
