Every summer Chevy Chase takes his family on a little trip. This year he went too far.
The Griswolds have planned all year for a great summer vacation. From their suburban Chicago home, across America, to the wonders of the Walley World fun park in California, every step of the way has been carefully plotted. So what if they lose all their money when their new car gets wrecked. And it's not too bad when Cousin Eddie deposits sour Aunt Edna in their back seat for a lift to Phoenix. But what really keeps Clark's eyes on the road is a flirtation with a mysterious blonde in a red Ferrari.
