Mid-1970s. The special department of the Ministry of Internal Affairs receives information that the Nazi executioner-collaborator Alex Fierce did not actually die at the end of the war, but still lives in the USSR. He has the blood of more than 2,000 compatriots on his hands. The hunt begins for the cruel traitor, but he does not sit still either. The traces leading to his current identity are constantly being cut off, suspects are replacing each other, and the number of victims is growing.
