Tim Kelly (James Ellison) is a Texan in the oil business who travels to Argentina to bid for some land. When his bid is unsuccessful, he teams up with colleague Duke Ferrell (Buddy Ebsen) to buy their employer a succes...展开sful racehorse, Lucero, in the hope that this will compensate for the failed bid. Tim falls in love with Lolita O'Shea (Maureen O'Hara), the daughter of the racehorse's owner, Don Enrique (Robert Barrat). Don Enrique is against selling Lucero, but when he realises his daughter is in love with Tim, he offers him the racehorse on the condition that he immediately returns to the USA. When Lolita realises Tim has left, she pursues him on horseback.
