The Larrabees are a wealthy family, living in a palatial estate on Long Island. Oldest brother Linus is the formal, dour businessman, running the family company. David is a playboy. Among the staff living on the estate is the family chauffeur, Thomas Fairchild, and his shy, awkward, plain daughter, Sabrina. Sabrina has had a crush on David for most of her life but he has hardly noticed her. Sabrina goes to study in Paris and comes back, two years later, a changed woman. She's sophisticated and beautiful and soon catches David's eye. However, David is engaged to Elizabeth Tyson, the daughter of a business mogul whose company Linus wants to merge with that of the Larrabees. If Sabrina wrecks the David-Elizabeth relationship it would likely spell the end of the business merger. Linus sets out to prevent Sabrina from getting in the way but in the process falls for her himself.—grantss
