The Black Sea resort town of Limansk is shaken by the brutal murder of local photographer Arkasha. Senior detective Marina Orlinskaya, like the rest, has no idea who harbored a grudge against everyone's favorite, but after conducting a search in his house, she understands: Arkasha was far from being so simple. All the evidence indicates that the brother killed the photographer, but all the shadowy forces of Limansk claim the legacy of the deceased.Investigating this case is becoming more and more dangerous: Marina is afraid for the lives of her nephews, abandoned in her care by her frivolous sister, and then she herself almost becomes a victim of an assassination attempt. But Orlinskaya will not retreat and will not calm down - even when she finds the killer. She feels that someone else directed the criminal's hand, someone too smart and cunning to leave traces. And this invisible man threatens not only Orlinskaya, but the whole quiet, lazy and careless Limansk.
