In Los Angeles, California, Norah Larkin (Anne Baxter) is a single woman who works as a switchboard operator along with her roommates, Crystal Carpenter (Ann Sothern) and Sally Ellis (Jeff Donnell). On her birthday, she decides to celebrate by dining alone at home, with the picture of her fiancé, a soldier serving in the Korean War. At the candlelight dinner table, she opens the latest letter from him and learns to her shock that he instead plans to marry a nurse he met in Tokyo.
