The film is dedicated to the life and exploits of Pyotr Markovich Koshka, the hero of the defense of Sevastopol during the Crimean War. His funny, tragic and entertaining adventures reflected the entire history of the Crimean war, and more broadly, the history of Russia. A man who managed to steal a beef leg from the cauldron of enemy soldiers, catch an enemy commander with a basket and defuse a cannonball with porridge will not leave anyone indifferent.
