Kirill's life is rapidly going downhill: for the past few years he has been living "on autopilot", every day mourning his happy past. Suddenly, he receives an offer he can't refuse. A crime boss hires him to find and stop a hitman who wants to kill him. For Kirill, this will not be just a job, but a long-awaited revenge - three years ago, through the fault of this man, his daughter died. But the killer does not kill himself - a deadly virus does all the work for him. He's already in the victim's blood, and no one knows how to stop him. Nobody but him - a former lawyer who, by the will of fate, found himself in the service of the mafia.
