The film begins with the carnage left by Japanese bombing in northeastern China, describing it as an unprovoked act of aggression. It then provides a brief overview of Chinese history and its connections and importance to Europe and North America. It discusses the modernization undertaken by the Republic and suggests that nascent development provoked Japan's attack. Japan's history of aggression is detailed, with United States's continuing exports of iron and steel to the country pointedly noted. The film takes pains to present the Chinese factions as united against the invaders and ends with some small Chinese victories to suggest a turning tide of battle, especially praising the 8th Route Army.
