Tomorrow, Monday, investigator Afonin will become part of the investigative task force, where the detectives are hunting for the “Tanner” - a maniac killer who skins his victims. But today, even though it’s a day off, he needs to investigate the strange death of two newlyweds. Thirty guests had already gathered in the house where the accident occurred. Afonin just has to interrogate the witnesses and let everyone go home. But with every minute of his stay in this place, the investigator begins to suspect that the “Tanner” himself is present among the guests, which means his future victim is also among them!
