Sabrina Fairchild is the young daughter of the Larrabee family’s chauffeur, Thomas, and has been in love with David Larrabee all her life. David is an oft-married, idle playboy, crazy for women, who has never noticed Sabrina, much to her and the staff’s dismay. Sabrina then attends culinary school in Paris and returns as an attractive and sophisticated woman.
David, after initially not recognizing her, is quickly drawn to her. David’s workaholic older brother Linus sees this and fears that David’s imminent wedding with a very wealthy woman, Elizabeth Tyson, may be endangered. If the wedding were to be canceled, so would a great corporate deal with the bride’s family. So Linus tries to redirect Sabrina’s affections, and in the process falls in love with her.
At the end, Sabrina sets off for Paris on a boat, after Linus has told her to leave and never come back. The next day Linus has second thoughts and decides to call off his brother’s wedding with Elizabeth and send David off on the ship to Paris with Sabrina. He calls a board meeting to announce his decision, but when it turns out that David has not boarded the ship, but instead intends to go through with the marriage, Linus realizes that he is in love with Sabrina. He manages to get on the boat, and the couple sails away together to Paris.
