An American girl finds love and laughter in the City of Lights in this romantic comedy. Maggie Scott (Ann-Margret) works as an assistant to Irene Chase (Edie Adams), a fashion purchaser for a large clothing store. Irene sends Maggie to Paris as her representative for the annual fashion shows of the major European designers; Irene has an ulterior motive, as her son Ted Barclay (Chad Everett) is infatuated with Maggie and she wants to keep him away from her. While in Paris, Maggie strikes up a romance with Marc Fontaine (Louis Jourdan), a handsome Frenchman who was once Irene's boyfriend. However, Maggie is also being pursued by American reporter Herb Stone (Richard Crenna). To add to the confusion, Ted decides to fly to Paris in an effort to win Maggie's heart once and for all. Jazz fans will want to keep an ear open for performances by Count Basie and Mongo Santamaria.
