Agent of the detective police

A provincial Siberian town is stirred by a series of mysterious crimes, including the murder of a famous German traveler. The case is under the control of the governor. It is being handled by the security department and the gendarmerie. But success is still with the criminal police - its chief, the seasoned investigator Fedor Tartishev, and the very young agent - Alexey Polyakov. They work in harmony, with enthusiasm and daring, often risking their lives. They leave the criminals no chance to escape punishment. Because a crime is always a crime, even if it is committed for noble purposes.
