Brigadier-General Bonner Fellers is sent to Japan as a part of the Occupation of Japan. He is tasked with arresting Japanese war criminals, including Prime Minister Hideki Tojo. Before he departs, he privately orders his Japanese interpreter, Takahashi, to locate his Japanese girlfriend, Aya Shimada. After arresting Tojo, the Supreme Commander for the Allied Powers, General of the Army Douglas MacArthur informs Fellers that Hirohito can be tried as a war criminal. Doing so could lead to a revolt, but the American people want the Emperor to stand trial for Japan's actions. MacArthur gives Fellers ten days to investigate the Emperor. When Takahashi informs Fellers that Aya's Tokyo apartment was bombed, he orders him to investigate her hometown, Shizuoka (city).
