On a dark night, Mykola Osovskyi, the director of the department store, approached the prosecutor's office investigator Artem Nagornyak and said that unknown people were watching him. An annoyed investigator does not believe him. Who in a small town can follow a famous businessman? If he had believed at once, they would not have killed Mykola the next day, and a few days later - his friend Andriy Sabanov. Killers driving a stolen car roamed the town. Osovsky's heir, his uncle Vsevolod Antoshevsky, almost became the third victim, but unknown people made a mistake with the poison. The death conveyor did not stop, and the investigator decided to lure the killer into a trap. Who did he find there? And he did not expect a surprise.
