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.

Little Mother is a 1929 Our Gang short silent comedy film directed by Robert F. McGowan. Produced by Hal Roach and released to theaters by Metro-Goldwyn-Mayer, Little Mother was the 87th Our Gang short to be released. A silent film, it followed Our Gang's first sound film, Small Talk, on the release schedule.

Joe Cobb is suffering through a toothache as well as having to babysit his little brother Rupert who won't stop crying. Every effort to calm Rupert is undone by an immediate commotion to wake him up. Joe rocks him to sleep, but then the neighbor starts playing his bass fiddle. Joe then rocks the cradle so hard it falls apart, and he trips and stumbles moving Rupert to the baby carriage, which subsequently rolls down hill through traffic with Rupert and a neighbor's monkey enjoying the ride.

Farina's mother is very ill and the mortgage is due. He tries to take over her laundry business, but the kids just wreck the clothes. Joe takes pity and devises a scheme to make money: the gang builds their own oil well.

Mary Ann Jackson and Bobby "Wheezer" Hutchins are the children of a widowed inventor who are forced to endure the cruelties of their stepmother and stepsister. The kids get even by rigging a few clever contraptions of their own. In the end the father sells a patent worth millions. Before that, the Our Gang kids bring out out the old "alum" gag, along with several other tried-and-true comedy bits.

As a joke, several members of the gang convince Farina, who is "brave but superstitious", that he's caused the demise of a young acquaintance and must therefore lay the body (actually still very alive) to rest in the old burying ground, under the watchful eye of "the graveyard witch". The joke backfires spectacularly on the pranksters.

While the other kids and animals find things to do on the farm, Farina becomes single-minded in his quest to do nothing at all.

The gang is playing around the railroad station, and Joe and Chubby's father, an engineer, lectures against the kids playing in such a dangerous area. True to his word, after Joe and Chubby's father leaves, a crazy man starts a train with most of the kids on it, save for Farina who is nearly run over several times. Once Farina manages to climb aboard himself, the kids attempt to stop the runaway locomotive, but have no luck until the engine crashes into a grocery truck. As it turns out, however, the entire incident is revealed to be a dream Farina had as Joe and Chubby's father lectured the kids about rail-yard safety.
