John Lawrence (Ronald Reagan) is a returning GI. Mary McKinley (Patricia Neal in her film debut) is the girl he left behind. But their reunion will have to wait: John has returned with cockney war bride Lilly Herbish (Virginia Field) in tow. It seems that John married Lilly as a favor to get her into the U.S., intending to divorce her so that she can wed her true love, John's old pal Fred Taylor (Jack Carson). Alas, Taylor has gotten married himself in the interim--and now John is stuck with Lillie. Somewhat cleaned up from Norman Krasna stage original, John Loves Mary is otherwise faithful to its source, right down to the all-smiles curtain call at the end.
