Moscow Spartakiad, 1936. The strongest team of wrestlers has been invited. The decisive duel: someone will win, someone will face defeat, and someone will face an unexpected turn of fate... Two martial arts masters. One, who studied the art of judo in Japan since childhood, is Vasily Oshchepkov. Another, who went through the Russo-Japanese War and is developing techniques for self-defense, is Viktor Spiridonov. Both are obsessed with the idea of creating a national struggle. This is how sambo was born. The tension of battles, the intrigue of competitions, the great era of discoveries and hopes - all this is intertwined with the destinies of the two great creators of sambo and their student Anatoly Kharlampiev.
