Private detective Kirill Vatsura walks over corpses. His client is killed as soon as she gets out of his car. The investigator with whom Watsura made an appointment is shot on the bridge before his arrival. The main suspect receives a call on behalf of Watsura, is called to the highway and is killed there with three shots to the head. And so on, literally corpse after corpse. The invisible, unknown, but all-knowing and all-seeing maniac killer is ahead of both the private detective and the police in everything, plays hide and seek and openly laughs at them. The police arrange a raid on Watsura, and Watsura is forced to run away from both the police and the killer. There can only be one way out of such a situation - to find it yourself, expose it and punish it.
