Hypochondriac elevator operator Danny Weems (Danny Kaye) and his best friend, Joe (Dana Andrews), are drafted. After basic training, the men discover that their friends, Virginia (Dinah Shore) and Mary (Constance Dowling), are nursing officers. Though Danny knows Virginia likes him, he likes Mary -- who in turn cares for Joe. When the men are ordered into duty, Mary is inadvertently trapped on board their ship. Trying to protect her friend, Virginia joins them as they set sail for war.
