Everything is planned. Everything is packed. And everything is about to go hilariously wrong. The Griswolds are going on vacation. In the driver's seat, of course, is Clark Griswold (Chevy Chase), an Everyman eager to share the open road and the wonders of family togetherness with his wife and kids. 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, it is indeed a wonder the Griswolds are together. There's never been a family vacation like it. Except perhaps for yours. And that helps explain why National Lampoon's Vacation remains so popular...and so very funny.
