The film follows Yukiko Koda, a woman who has just returned to Japan from French Indochina, where she has been working as a secretary. Yukiko seeks out Kengo, with whom she had an affair in Da Lat during the war. They renew their affair, but Kengo tells Yukiko he is unable to leave his wife. Brightly lit flashbacks of their time in Indochina contrast with the sombre tones of the film's present.
