Burning Mountain River.

The three Amaba brothers are second-generation Japanese Americans, whose allegiances are torn by the bombing of Pearl Harbor. Determined to show his loyalty to his adopted country, Isamu volunteers for the U.S. Army and is shipped off to fight in Europe. A second brother, studying in Japan at the outbreak of hostilities, is conscripted to fight against the Americans as a Japanese soldier. The third brother Kenji (Matsumoto) avoids conflict by enlisting as a military interpreter, in which capacity he witnesses the war crimes trials that followed Japan's defeat.
