Advantage was taken of the fact that a floral parade was being held at Pasadena, Cal. in which the Keystone car was entered and won second prize, to produce a comedy film around the incident. Fred Mace and Mabel Normand are invited to take part in the parade, and Mack Sennett plans to keep her away and take her place Accordingly Mabel is locked up in her dressing room. But she escapes after considerable difficulty. She rushes to the line of march and makes frantic and amusing efforts to catch the Keystone automobile while the two sleuths attempt to dodge her. Mabel gets into difficulties with the police who are endeavoring to maintain order, and is championed by Ford Sterling, who is among the spectators.
