Suddenly, right on the street, prosecutor Kravtsov recognizes the White Guard soldier Vinter, who was sentenced to death. The sentence was to be carried out by Red Army officer Prokopchuk, but as it turned out, he took pity on the prisoner and released him. Employees of the GPU (State Political Directorate) track down Wynter and the group of "smugglers and saboteurs" he led. In order to catch the state criminal, Prokopchuk asks to join the coast guard. He tracks down Wynter as he returns from abroad on a schooner. In a desperate fight, Prokopchuk dies along with his enemy.
