Unbribable prosecutor Evgeny Pak goes against the system by taking on the investigation of a brutal murder of a homeless man, in which a company of spoiled wealthy teens is involved.
While Pak, together with a group of young interns, makes their way through layers of deception, bribes, and deliberate obstacles, investigator Alla Surkova discovers in a nearby forest a horrifying grave—kept secret for four years.
At the same time, Lera Medved tries to understand the circumstances behind the mysterious death of a ballet academy teacher, where Pak’s daughter studies.
Gradually, the scattered stories tighten into a single knot: it turns out that all these crimes are connected and lead to one person—the calculating mastermind, a true evil genius.
