Las fronteras del amor

The famous and much-loved opera singer, Miguel Segovia, has grown tired of the publicity tricks and the tour that his manager Harry has planned for him, so he returns to his ranch in Mexico. The ranch hands greet him excitedly, and the morning after an all-night party, he rides a horse to the cabin of the ranch's sheepherder José López. José, who has never met Segovia, tells the stranger that he needs to become a cowpuncher in order to marry his girl friend María, the daughter of the ranch's groom. Looking to get away from people, Segovia tells José to take his horse and promises to tend the sheep while José fulfills his wish. While Segovia is playing in a nearby field, a plane, sputtering from lack of gas, lands, and the pilot, Alice Harrison, of the high-society Harrisons in California, steps out. She tries to get Segovia, who says his name is José, to obtain fuel for her plane because her family will be worried if she does not return soon. He refuses but offers to let her stay in his cabin, which she declines, because it is too filthy, and walks back toward the plane. The real José, having been told who the stranger is, returns to his cabin only to be sent back for fuel by Segovia. Frightened by an animal's howling, Alice returns to the cabin, where she spends the night sleeping in a chair. The next day, Alice tries to bribe Segovia to go for fuel by offering him her Victrola. He is unimpressed until she tap-dances to one of her records. José returns with the fuel, but Alice fears it is too late in the day to leave, so she stays another night and falls in love with Segovia; however, because she believes that they are from different social classes, she leaves at dawn before Segovia can stop her. In Los Angeles, an old beau, Otto Van Ritter, who does not know how to enjoy himself, proposes marriage, which Alice refuses. She confides to her Uncle Fred, who advises her to follow her heart. Meanwhile, Harry, having located Segovia, talks him into returning to the tour. Alice, having sent a letter to "José," receives an angry letter from María telling Alice of José's engagement to her. Otto proposes again and this time Alice accepts. Segovia reads about her engagement and goes to Alice's house, where he is told by her that it is none of his affair. Later, she overhears a radio broadcast of his concert and believing the voice to be José's, rushes to Mexico to follow her heart. Alerted to her trip by Uncle Fred, Segovia manages to delay her flight and reaches Mexico before her. When she arrives, he proposes to her; she accepts and José sings happily at their wedding.
