Young "Flip" Gayley (Patti Brady) thinks her parents will reunite if her father, Phil (Errol Flynn), believes her mother, Ellen (Eleanor Parker), has a romantic life. Ellen, however, isn't seeing anyone. Flip sends her soldier pen pal a photo of her mother, hoping he'll believe he's been corresponding with Ellen all along. Ellen and the soldier soon find themselves in the same restaurant as Phil. Instantly jealous, Phil schemes to replace the man he fears is about to steal Ellen's heart.
