The end of the “dashing nineties”. In the village of Danilovka, Staronovo province, a local emergency occurs: a very dangerous disease is discovered, common to animals and humans. The veterinary authorities immediately indiscriminately blame the local veterinarian Andrei Berezintsev for the incident. It would seem that he should give up, come to terms with what happened and repentantly sprinkle ashes on his head. But Andrei is a grated kalach, He understands that they “hang dogs” on him for a reason. Behind all this lies some kind of murky scam. He begins his own investigation and finds out who actually spread the infection in the area. The ending of the "veterinary detective" is somewhat unexpected. It may not be too similar to the textbook “triumph of justice,” but the main character is not offended by fate.
