Three men with strange nicknames - Joker, Warrior and Poet - appeared in my life recently, instantly turning everything upside down. Our close-knit team investigates crimes. And now we have been approached by a new client, a wealthy businessman Pavel Klyuchnikov, who lives in the village of Cherkasovo, where sinister things are happening. It all started with the disappearance of pets - cats, dogs... Then a friend of Klyuchnikov’s daughter drowned. He suspects murder and fears for the life of his daughter. And something unusual is happening to me: for some time now I have been noticing various signs, I have nightmares at night and there is a feeling that someone is playing with us. Someone is always standing behind you...
