Former riot police officer Ivan Petrovich Kalugin (Igor Bochkin) has long retired. He lives in a quiet fishing village with his family - his wife Katya (Anna Legchilova), daughter-in-law and eldest son Artyom (Mikhail Vasiliev). As an exemplary family man and a good boss, Petrovich controls not only his family. Petrovich drives a longboat and fishes together with Artyom, and he solves the neighbors' conflicts and monitors local poachers in his spare time. In the village the inhabitants are afraid of him, but respect, because they know: Petrovich will always act fairly and honestly. But the measured rural life unexpectedly ends when the second Petrovich's son, Semyon (Arthour Sopelnik) returns to the family. Unable to take root in a big city, a prodigal son has got into huge debts and now he is hiding from creditors.
