Every summer Chevy Chase takes his family on a little trip. This year he went too far.

Everything is planned, packed and about to go hilariously wrong. The Griswolds are going on vacation. In the drivers seat is Clark Griswold (Chevy Chase), an Everyman eager to share the open road and the wonders of family togetherness. Myriad mishaps, crude kin (Randy Quaid), encounters with a temptress (Christie Brinkley), financial woes, Aunt Edna (Imogene Coca) on the roof, one security guard (John Candy) and 2,460 miles later, its a wonder the Griswolds are together. Theres never been a family vacation like it. Except maybe yours.
