Hank Twirling's (Mature) circus is failing and to get a bank loan he must put up with the presence of bank officer Sherman (Buttons) and Helen (Fleming), the publicist that Sherman hires to drum up business. But Hank has bigger problems since a saboteur is at work--letting the lions loose, starting a fire, and even causing a deadly train wreck. Fairly typical circus story featured many of the famous acts of the day.
