A quiet seaside town is shaken by murders committed with particular brutality. Investigator Irina Shumskaya is assigned to the case and decides to seek help from the talented psychologist Andrey Vysokov. An experienced specialist, he has a unique gift for seemingly getting inside a criminal’s mind, helping him understand their logic and next moves. After examining the crime scenes and the victims’ bodies, Andrey shocks everyone by stating that the mysterious killer will continue the hunt, and the next target will be... a police officer.
Irina wants to prevent another attack, but the head of the department, displeased by the involvement of the eccentric psychologist in the investigation, is about to interfere with her work.
