This is the story of a serial killer nicknamed the Headhunter, who was feared by the entire country. The horror and dissatisfaction with law enforcement are so great that the authorities are seriously considering a genetic testing project that would allow for the 99% accurate identification of the psychopathy gene in embryos. Ten years later, the monstrous events are still closely intertwined with the fate of a professional detective, a female producer, a police officer, and a troubled schoolgirl.
