Farina, Joe, and friends use dogs to power their "roadsters," but following a lesson from the head of the Be Kind to Animals Society, they make it their cause to rescue animals from bad treatment. Joe even manages to find patience for a nagging flea that persists in biting him. Meanwhile, Wheezer, who has been tormenting animals with his games, dreams that the animals have turned the tables on him.

The Rascals have a boxing arena that could pack them in if they could find fighters who would actually mix it up. Harry and Farina notice a rivalry between two very large young kids, Joe and Chubby, that would fill the bill if only the two heavyweights would put aside their gentle natures. Farina gets an idea: tell each of the lads that the other will take a dive in the second round. So the fight begins and the stands are filled; but will the combatants actually throw a punch? Ernie has one more trick up his sleeve to get the fists flying and the crowd on its feet. Sweet science indeed.
