A somewhat prim and proper Englishman is hired as the tutor to the son of the Japanese ambassador. His life changes when he and the boy are kidnapped by terrorists for political purposes.

Air Force Major Lloyd Gruver (Marlon Brando) is reassigned to a Japanese air base, and is confronted with US racial prejudice against the Japanese people. The issue is compounded because a number of the soldiers become romantically involved with Japanese women, in defiance of US military policy. Ordinarily an officer who is by-the-book, Gruver must take a position when a buddy of his, an enlisted man Joe Kelly (Red Buttons) falls in love with a Japanese woman Katsumi (Miyoshi Umeki) and marries her. Gruver risks his position by serving as best man at the wedding ceremony.
