Sabrina and Stephanie Longworth are twins. Sabrina married a wealthy English aristocrat and divorced him. She now runs a successful antiques business in London. Stephanie married Garth Anderson, a scientist and university professor. She stays at home in the suburbs with their two children and envies her sister's jet set lifestyle. Stephanie's desire for a more exciting life is putting a strain on her marriage.
Stephanie gets Sabrina to switch places so she can have some fun but does not want Garth to know. Garth did not like Sabrina when he met her and thinks she is the cause of Stephanie's dissatisfaction with her life. Sabrina quickly adjusts to Stephanie's home life, and gets to know and like Garth. Stephanie finds she is good at the antiques business. But just before they are to switch back, Sabrina breaks her leg and the deception has to continue. Stephanie does not mind because she has started an affair with one of Sabrina's friends. Nor is Stephanie upset when Sabrina confesses she could not say no when Garth wanted to make love. The longer Sabrina lives with Garth, the more she falls in love with him. Garth feels like he is falling in love with his wife all over again as she takes an interest in his work and encourages his dreams instead of wanting him to make more money.
Then Stephanie is killed when her lover's yacht explodes. Sabrina cannot bring herself to tell Garth it was really Stephanie and she tries to carry on the deception because she loves Garth too much to have him leave her once he learns the truth.
