An heiress searches for true love while vacationing in Brazil.

After conducting a high-powered meeting with the board of directors of her New York corporation, wealthy, beautiful Nora Taylor rushes to her session with analyst Lionel Y. Newman, to discuss her conflicted feelings about her boyfriend, Paul Chevron. Nora, who became rich when her mailman father struck oil, questions whether the men she dates truly love her, or merely desire her $37 million fortune. Newman points out that Paul has $48 million of his own, and predicts that the assertive businessman will take charge of the situation and insist that Nora marry him. Meanwhile, Paul consults a female analyst for advice on proposing to Nora, and is urged not to be too forceful. That evening, over dinner at a nightclub, Paul brings up the subject of marriage but, acting on his analyst's advice, tells Nora not to give her answer until he returns from a polo trip to Brazil in three weeks. Before she can reply, Nora is asked to dance by a Brazilian man, who tells her that the atmosphere in Brazil makes all men passionate about women. Curious to see what effect the country will have on Paul, Nora secretly flies to Brazil, accompanied by her secretary, Anne Kellwood. They check into the same hotel as Paul, and when Nora goes to her beau's room to surprise him, she finds him laid up with polo injuries. The following day, while Paul is looking at some horses, Nora is taken with their owner, the handsome Roberto Santos. After the horses are shown, Nora strolls back to the stables, and Roberto seizes her without a word and kisses her passionately. That evening, Nora engages Howard G. Hubbell, from the American Embassy, to teach her Portuguese. She then calls Newman, who tells Nora to do exactly what she feels like doing. Nora promptly cancels her dinner date with Paul and, armed only with the Portuguese phrase "You have beautiful horses, darling," returns to Roberto's villa. There she finds a party in progress, and is surprised to discover that Roberto speaks English. Roberto teaches Nora to dance the samba, and when she gets a thorn in her foot, carries her back to the home he shares with his grandfather, Eduardo. Nora returns to her hotel room in a happy daze that night and tells Anne to take a few days off. Meanwhile, Roberto tells his grandfather that he wants to marry Nora. The following morning, Nora informs Paul that she intends to marry Roberto. Paul takes the news calmly, and Nora invites Roberto and Eduardo to dine with them that evening. After their guests leave, Paul observes that a proud man like Roberto probably will not take the news of Nora's fortune well. After again calling Newman for advice, Nora tells Roberto about her money, and he is delighted by the news. Roberto's enthusiasm about her money begins to trouble her, however, and he offers no reassurance, telling Nora she will simply have to trust in his love for her. Nora devises a plan to test Roberto's sincerity, and on the night of their engagement party, she happily tells him that she is giving away all of her money. Roberto is displeased, and Nora ends their engagement and leaves the party with Paul. Back at the hotel, Paul calls his analyst, who instructs him to be masterful and sweep Nora off her feet, then goes back to her patient, who happens to be Newman's frustrated wife. Paul marches into Nora's room and tells her they will marry that night, but Nora sadly admits to Paul that she does not love him. After Paul leaves, Anne reveals that she is in love with Paul, and Nora gives her secretary her blessing. When Anne remarks that Paul's money does not intimidate her, adding that only the person who has money has to worry about it, Nora suddenly sees her own situation in a new light. She goes to Roberto's villa and states her intention to marry him on her own terms--namely, that she be allowed to give all her money to him.
