A new case arrives at the operational investigation department - fashion designer Inga Malinina was killed and raped. The murder has a pronounced handwriting - a white rose is left on the pillow, the corpse is wrapped in a blanket, all objects in the apartment are meticulously washed, and the door to the room has been broken with a fist. Employees of the store, where Malinina's dresses were sold, claim that Inga was actively looked after by the store manager Dmitry Sundukov, who had a fresh hand injury.

A young guy Sergei Kovalenko helps the investigation to expose Roman Barinov, a pedophile with many years of experience, who repeatedly persuaded Sergei to have sex. But at the last moment of the operation, Kovalenko breaks down and warns Barinov that their conversation is being recorded on tape. Barinov does not have time to escape, and he is detained, but nothing illegal sounded in the recording and he had to be released. Soon, the investigation finds another former victim of Barinov - Valery Skvortsov, who talks about Roman's strange habit of giving the boys, when parting with them, videos of their joint sexual encounters.
