"Moonzund" is based on a novel by Valentine Pikul. It is a great war film about an incident that happened during World War I on a small island Moonzund, several miles of shore from Saint Petersburgh, Russia. Russian sailors defended this island and the city of Saint Petersburgh from the advancing German Fleet. This movie also explores the events leading to the Communist Revolution in 1917 and shows different mind sets of sailors and officers of the Russian Navy, and their loyalty to each other, and Russia.
