Billy Wilder directs the lighthearted romantic comedy Sabrina, based on the play by Samuel A. Taylor. Sabrina Fairchild (Audrey Hepburn) is the simple, naïve daughter of a chauffeur, Thomas Fairchild (John Williams). They live on an estate with the wealthy Oliver Larrabee (Walter Hampden) and his two sons: workaholic older brother Linus (Humphrey Bogart) and fun-loving younger brother David (William Holden). Sabrina adores the charming David, but he thinks of her as just a kid. Her father sends her away to Paris for chef school, where she meets Baron St. Fontanel (Marcel Dalio), and she returns a worldly, sophisticated woman. David immediately falls for her, but he is already engaged to marry heiress Elizabeth Tyson (Martha Hyer). Sabrina wants to break up the wedding in order to finally catch the man of her dreams, while Linus fights to keep the marriage on in the interest of family business and Mr. Tyson's (Francis X. Bushman) fortune. In order to keep Sabrina away from David, Linus pretends to court her himself. In doing so, they eventually realize their true feelings for each another.
