The film tells the story of a grounded American pilot during the Second World War who learns about the noble spirit of the Chinese poeple when he is rescued by the communist-led Chinese army after an emergency landing near the Great Wall. On the way to the Communist base, the pilot falls in love with a girl soldier whose lingering memory of being raped by the Japanese makes her a determined fighter. Half a century later, the American pilot returns to the Yellow River to pay his respects to the native people who rescued him.
