Retired millionaire Benjamin Dingle (Charles Coburn) arrives in Washington, D.C. as an adviser on the housing shortage and finds that his hotel suite will not be available for two days. He sees an ad for a roommate and talks the reluctant young woman, Connie Milligan (Jean Arthur), into letting him sublet half of her apartment. Then Dingle runs into Sergeant Joe Carter (Joel McCrea), who has no place to stay while he waits to be shipped overseas. Dingle generously rents him half of his half.
