Aleksandr Kron

A Jewish tannery worker, Nahum Beychik, invents a machine that makes hard work easier in leather tanning. A private entrepreneur, former kulak Lopatin, tries to buy the invention and use it for his own selfish interests. Having met with a decisive refusal from Nahum Beychik, the kulak exploits the anti-Semitic sentiments of the backward part of the workers and, with the help of his accomplices, hooligans and truants, tries to kill the inventor.

About the heroism and endless devotion to the Motherland of military sailors in Leningrad during the Great Patriotic War.
