Plot

Although she initially rejects an offer by Joe Backett to become his business partner at the Neptune swimming suit design company, aquatic ballet dancer Eve Barrett changes her mind when she considers the publicity potential of the job. One day, Joe learns that a South American polo team will be playing a big match in town, and he and Eve begin planning a swimming spectacle for the event. Eve tells her man-crazy sister and roommate Betty about the South American team, and Betty immediately seizes upon the idea of finding herself a date among the players. Meanwhile, Jose O'Rourke, the handsome playboy captain of the polo team, seeks relief for his injured arm from Jack Spratt, a bumbling masseur, who complains to Jose about his lack of success with women. During the massage, Jose gives Jack advice on how to attract women, stressing the importance of speaking to women in Spanish, which he calls the "language of love." Later, while looking for the famed South American team captain, Betty accidentally mistakes Jack for Jose. Jack does not reveal his identity to Betty and accepts her invitation to visit her at her house.
