Many serials about investigators are based on real cases, but at the same time the identity of the investigator who uncovered this case remains behind the scenes. On the screen, we see not a real person, but a certain collective image. It was. But it won't be like this anymore. In this 12-episode serial, the prototypes of the three main characters were three investigators of the Main Investigation Department of the Investigative Committee of the Russian Federation. All of them are people of high ranks and really geniuses of their work. All the cases used in the series are real, for which the perpetrators are found and convicted. The series will give the viewer not only an exciting detective intrigue based on facts from life, but also reveal the identity of the investigator, usually remaining "in the shadow of" the case itself.
