Young Ricardo Quintano voyages from Argentina to New York to sell some of his father's prize horses. Before leaving, Don Diego instructs his son that no steeds are to be sold to Binnie Crawford or any member of her family because her brother Willis cheated him years earlier. Upon arriving in New York, Ricardo falls in love with Glenda Crawford, but when he learns that she is Binnie's niece, he refuses to sell her the horse she wants to buy and hurriedly returns to Argentina. Perturbed, Glenda follows him, accompanied by Binnie. The couple meet again in Argentina, where they confess their love for each other, and Ricardo introduces Glenda to his father as "Miss Cunningham." Glenda encourages Ricardo to enter his father's prize jumper, Furioso, in a race, against Don Diego's wishes. Soon after, while attending a horse show, Don Diego discovers Glenda's true identity and disowns his son. His bad mood is then compounded when Furioso refuses to jump and runs off the field. To make up for the humiliating defeat of his father's jumper, Ricardo enters Furioso in the big race, and when the horse wins, Don Diego changes his mind about racing horses and about Glenda.
