Investigator Anokhin offers his friend, journalist Yeltsov, to help in the search for criminals. At the same time, a high-profile bank robbery is taking place in Yerevan, which is being carried out by a specially released bear swallowtail. At first glance, the two cases seem completely unrelated. Plunging deeper into the investigation, special correspondent Yeltsov realizes that he has found a conspiracy, the bloody threads of which stretch to the highest echelons of power.
