This peppy Monogram meller stars Robert Armstrong as a big-city newspaper reporter. After getting a bonus, Armstrong over-celebrates and wakes up in faraway St. Louis without a penny to his name. He finagles passing-stranger Maxine Doyle into posing as his wife so that he'll be able to get a hotel room. While thus occupied, Armstrong finds time to solve a local mystery and secure another bonus that will enable him to marry Doyle for real. Mystery Man was directed by Leo McCarey's kid brother Raymond, a veteran of the Hal Roach and Columbia 2-reel comedy factories.
