Valery Shtukin, dismissed from the criminal investigation department, begins to work in the structure of the former crime boss Yungerov, who does not even suspect that in fact this is how an active police officer was introduced to him.

Yungerov's student Egor Yakushev successfully begins his service in the criminal investigation department in place of Shtukin. There is a conflict between the young people over a woman, an employee of the prosecutor's office, with whom Yegor is in love, and who goes missing.
