After four long years apart, there are so many things returning World War II soldier John Lawrence wants to tell his sweetheart, Mary McKinley. That he loves her. That he's missed her. That he's married. No wait, honey, there's an innocent explanation! Ronald Reagan is John and film-debuting Patricia Neal is Mary in a tale of a G.I. whose good deed ' marrying his buddy's British girl so she can come to America ' turns out to be a bad idea when he discovers the buddy has already tied the knot with someone else! Based on Norman Krasna's hit Broadway play, John Loves Mary is an airy, witty farce, a wedding cake of comedy and romance.
