Kirill's life is rapidly going downhill: for the last few years he has been living "on autopilot", mourning his happy past every day. Suddenly, he receives an offer that he cannot refuse. The crime boss hires him to find and stop the killer who wants to kill him. For Kirill, this will not just be a job, but a long—awaited revenge - three years ago, his daughter died because of this man. But the killer doesn't kill himself — a deadly virus does all the work for him. It's already in the victim's blood, and no one knows how to stop it. No one except him, a former lawyer who, by the will of fate, found himself in the service of the mafia.
