After three similar murders, it becomes obvious: in Shelково a serial killer—an obsessive maniac fixated on mystical city legends—is at work. If he stays true to himself, another murder will happen any day now, and the police have almost no leads. The only clue comes from Vlad, who, while drawing an old well standing in the middle of the forest, suggests that the next crime must be connected to that place. Meanwhile Vlad is still trying to figure out what happened on the day he got into an accident and lost his sight, and at the same time to sort out the complicated, increasingly tense relationship with Yulia. Yulia, for her part, is trying to understand what’s causing the changes in her. But all the heroes will have to, for a while, forget their other problems—when the one who lives in the well starts hunting them.
