Little Tokyo, U.S.A.(1942)

Filmed in the months immediately following Pearl Harbor, 20th Century-Fox's Little Tokyo USA is 63 minutes' worth of speculation about prewar Japanese espionage activities. Los Angeles cop Preston Foster suspects that there's dirty work afoot in the city's Japanese community, but no one will believe him except for intrepid girl reporter Brenda Joyce. When the spies frame Foster on a trumped-up murder charge, Joyce does a little detective work herself. The enemy agents are rounded up just before they can do any real damage. Because of its strident insistence that most (if not all) Japanese-American citizens were secretly loyal to the Rising Sun, Little Tokyo USA is seldom seen these days.
