 
            WWII. The Nazis subject the radio station on Bezymyanny Island to a brutal bombardment and soon land a landing force. The enemy mercilessly destroys all life, but the radio station continues to operate—meteorologist Asya has installed a spare radio on an abandoned schooner. The Soviet warship and seaplane continue to fight the invaders.
