This film portrays the lives of a US Army engineer squad in China during WW II. Their mission is to delay the advance of the Japanese Army. They must blow up bridges and ammo dumps along a long mountain road while dealing with a never ending line of Chinese refugees. James Stewart finds love with a beautiful Chinese widow. He must deal with his personal feelings toward a woman, a foreign people and the challenges of command. Not one of your best Jimmy Stewart movies but well worth a look.
