Muriel Box directs this 1950s comedy in which a writer of erotic fiction encounters trouble when her chauffeur gets his hands on her latest manuscript. Judith Wynter (Margaret Leighton) is a successful author of romantic fiction who is always on the lookout for new ideas. When she and her husband (Ralph Richardson) take on an Italian chauffeur, Carlo (Carlo Giustini), she is inspired and quickly puts pen to paper on a fantasy built around a lady's driver. However, when Carlo discovers the manuscript he takes it a little too literally and begins to harbour designs on his employer. Can Judith, Carlo and co. untangle themselves from the surprisingly intricate web of fantasy and reality in time to avert disaster?
