Chantal Stacy (Sandra Dee) is the daughter of Germaine Stacy (Micheline Presle), a former French showgirl, and John Stacy (John Lund (actor)), a conservative Boston antiques dealer, who met in Paris. Chantal was the product of their "soufflé-and-beans romance." Her father worries about her French part getting pregnant, before her Boston part gets married; a foghorn sounds every time a man gets too close to her.
