Due to a housing shortage in Washington, D.C., during World War II, Connie Milligan (Jean Arthur) agrees to rent part of her apartment to wealthy retiree Benjamin Dingle (Charles Coburn) and soldier Joe Carter (Joel McCrea). Although Connie is engaged to the unexciting Charles Pendergast (Richard Gaines), she becomes fond of Joe. When Dingle notices their interests in each other, he attempts to play matchmaker -- but instead causes problems for the entire apartment.
