Elmer (Keaton), a member of the idle rich, is smitten by working girl Mary (Sally Eilers), who will have nothing to do with him. When Elmer's chauffeur gets caught up in an army recruitment drive and quits, Elmer goes to an employment agency to find a new driver and accidentally enlists in the army. Elmer learns that Mary is on the base to entertain the troops and learns that his drill sergeant, Brophy (Edward Brophy), is also interested in Mary.
