An echelon of soldiers arrives at the Far Eastern station, including a reconnaissance platoon, which will have to find the plant. The platoon includes Sergeant San Lee, nicknamed Sanya, and his colleague Kuzmin, a former student at the Institute of Oriental Languages. To get information about the location of the plant, the scouts need to get to Harbin and establish contact with the Soviet agent Rybak.

Yuri Bragin, after a year-long business trip, where he, as part of an investigation team, was investigating a high-profile case, returns to St. Petersburg. When he returns, he learns that the current head of the First Investigation Department of the First Directorate of the State Investigation Department, Vadim Maltsev, is retiring. With a high degree of probability, it is Bragin who will be offered his place. But Yuri is not a careerist and the position of the boss is not the goal of his life.

This time in one of the cities of the Leningrad region, where two girls were killed with a difference of a week.
