El propietari d'una mula que parla es fica en embolics per culpa d'uns gàngsters.

In this funny sequel to the popular Francis the Talking Mule, the talkative Mule and his pal Peter get a job working on a horse-breeder's ranch. They end up saving it from financial ruin when Francis, who has the inside track with the racehorses, provides Peter with names of the winners before the races are run. Sure enough Peter finds himself with a fistful of cash and uses it to buy a racehorse for the farm. Unfortunately, the horse he chooses is suffering from a debilitating lack of confidence. When not dealing with the mare, Peter finds time to court the horse breeder's niece and trying to avoid the gangsters who want in on the winnings.

Patrick ne peut conserver un emploi car, dès qu'il parle de son mulet, doté de la parole, on le croit fou. Francis rencontre un sien cousin, cheval de courses, Zephyr. Grâce à Zephyr, Francis peut fournir à Patrick le nom des gagnants de chaque future réunion hippique. Mais la chance insolente de Patrick excite les curiosités...

Peter conosce un colonnello in pensione, proprietario di una scuderia. Questi si trova in cattive acque e Peter, che subisce anche il fascino della figlia, vuole aiutarlo. Entra in scena Francis, il mulo parlante che suggerisce a Peter i risultati delle corse facendogli vincere una grossa somma.
