An Indiana family embarks on their dream vacation to France. The Willard family, led by Harry (Fred MacMurray) and Katie (Jane Wyman), bring their three children along to experience a slice of continental culture abroad. Amy (Deborah Walley) is the lovestruck teenager whose brother Elliott (Tommy Kirk) is easily as eager for love. Younger brother Skipper (Kevin Corcoran) is the mischievous moppet who is always getting lost. Elliott is mesmerized by a pretty French maid, Amy is wooed by a wealthy teen, and Katie fends off the advances of an amorous playboy. From Paris to Monte Carlo, the Willard family experiences culture shock firsthand and realizes quickly they are not back home in Indiana. This Walt Disney production, while focusing on less childlike themes than in other films, still managed to take in five million dollars in its initial domestic release.
