It's 1986, and teenagers are being murdered one after another in the area of government dachas on the Rublevskoye Highway. Valery Kozyrev, an intelligent investigator, his daring partner from Rostov, Yevgeny Bokov, and a young investigator named Natalya Dobrovolskaya begin their investigation, unaware of how it will change their lives. The only witness who can identify the killer is a schoolboy named Igor, whose parents are not pleased with their son's involvement with the police.
