Stationed in Japan during the Korean War, U.S. Air Force Major Lloyd Ace Gruver falls for the beautiful Japanese actress Hana-ogi (Miiko Taka). However, he is hesitant to pursue the relationship due to the unfortunate example of his crew chief, Airman Joe Kelly (Red Buttons). Kelly, against official military advice and the prejudices of his commanding officers, married a Japanese woman, Katsumi (Miyoshi Umeki), and his military career has suffered ever since.
