Jimmie gets a wire from his uncle that the latter is about to present him with a new aunt and will also donate to him $10,000 if Jimmie will bring his fiancée and make it a double wedding. It is stipulated, however, that Jimmy must have the girl on hand within a half hour. Jimmie, the girl and the girl's parents hustle into an auto and proceed to break all speed records until they are humbled by a trio of motorcycle cops. By a ruse they get possession of the motorcycles and the chase starts all over again. Twice they step into the wrong wedding ceremony, but eventually land right, only to run into a melee from which they are all sentenced to do thirty days, with the double wedding scheduled to follow.
