1986 In the area of government dachas on the Rublevsky highway, teenagers are being killed one by one. Intelligent investigator Valery Kozyrev, his daring partner from Rostov Yevgeny Bokov and a very young investigator Natalya Dobrovolskaya begin an investigation, not even suspecting how much it will change the fate of each of them. The only witness who can identify the maniac is the schoolboy Igor, whose parents are not at all enthusiastic about his son's contacts with the police.
