The Griswolds are going on vacation. In the driver’s seat is Clark Griswold (Chevy Chase), an everyman eager to share the open road and the wonders of family togetherness with his long-suffering wife (Beverly D'Angelo) and their two frustrated teens. After myriad mishaps; 2,460 miles; and a run-in with a hapless security guard (John Candy), it's a wonder the Griswolds are still together. There's never been a family vacation like it.
