Set in wartime (WW II), this film finds the fat guy, skinny guy comedy duo not much good at any attempted professions; they can't even enlist in the war effort. None of the services want them. But they do become air raid wardens, at least for a while, until their misadventures continue. They get all boozed up and are kicked off the air raid squad, too! But things get better when they thwart a spy ring and save the day.
