Output: Clark Griswold, wanting to spend more time with his wife Ellen and children Rusty and Audrey, decides to lead the family on a crosscountry expedition from the Chicago suburbs to the southern California amusement park Walley World, billed as Americas Favorite Family Fun Park. Ellen wants to fly, but Clark insists on driving, so he can bond with his family. He has ordered a new car in preparation for the trip, but the dealer claims that it will not be ready for six weeks. Clark is forced to accept a Wagon Queen Family Truckster, an ugly, outsized station wagon, as the car he brought to trade in has already been hauled away and crushed. During the familys travels, they run into numerous mishaps, such as being tagged by vandals in a rundown area of St. Louis, while Clark is tantalized numerous times by a beautiful young woman driving a flashy red 1983 Ferrari. They stop in Coolidge, Kansas to visit Ellens cousin Catherine and her husband Eddie, who foist cranky Aunt Edna and her mean dog Dinky on the Griswolds, asking them to drop her off at her son Normans home in Phoenix. After stopping at a decrepit and dirty campground in Colorado for the night, Clark forgets to untie Dinkys leash from the bumper before driving off the next morning, killing the dog. A state trooper pulls the Griswolds over and angrily lectures Clark over animal cruelty but accepts Clarks apology; Edna learns of her dogs death and becomes more irate with Clark. Exiting Colorado, Ellen loses her bag which had her credit cards, forcing Clark to have to cash a check for future spending. While Ellen and Clark argue during a drive between Utah and Arizona, they crash and become stranded in the desert. After setting off alone in the desert to look for help, Clark eventually reunites with his family, who have been rescued and taken to a local mechanic. The mechanic extorts the remainder of Clarks cash only to make the car barely operational. Frustrated, they stop at the Grand Canyon; when Clark cannot convince a hotel clerk to cash a personal check because HIS credit card was reported stolen, he takes cash from the cash register behind the clerks back and leaves the check. Leaving, they find that Aunt Edna has died in her sleep. They tie the deceased to the roof of the car, wrapped in a tarpaulin. When they reach Normans home, they discover he is out of town and leave Ednas body at the back door. Having enough of the roadtrip and of the mishaps they encountered, Ellen and the children want to go back home, but Clark has become obsessed in reaching Walley World and they continue on. After an argument with Ellen, Clark eventually meets the Ferraridriving blonde beauty at a hotel and goes skinnydipping with her in its pool, but they are discovered by the family before anything untowards can transpire. Ellen forgives Clark, and the couple goes skinnydipping as well. Despite the familys misfortunes, they finally arrive the next day, only to find that the park is closed for the next two weeks for repairs. Finally slipping into madness and realizing that all his efforts have been for nothing, Clark buys a realisticlooking BB gun and demands that park security guard Russ Lasky take them through Walley World; Ellen and the kids follow, attempting to placate Clark. Eventually, an LAPD SWAT team arrives, along with park owner Roy Walley. Roy understands Clarks impassioned longing to achieve the perfect vacation, bringing back memories of his own familys vacation headaches. He decides not to file criminal charges against the Griswolds and lets the family – and the SWAT team – enjoy the park as his guests.
