Capodistria, 1915. Captain Nazario Sauro, an officer in the Austrian Navy, is one of those patriots who militate for Italy to enter World War I. When he is about to be arrested by the Austrian authorities he chooses to desert. Once in Venice he enlists in the Italian Navy and becomes an officer in a submarine where his perfect knowledge of the coast of Istria proves particularly helpful.
