Vegas Vacation

After discovering a food preservative that keeps perishable items fresh for years, Clark Griswold finally earns the sizable cash bonus promised to him in the previous film from Frank Shirley. He announces to his family that he is taking them on vacation to celebrate and renew wedding vows with his wife Ellen. Excitement wanes, however, when Clark says they are headed to Las Vegas. His wife, Ellen, and teenage daughter, Audrey, have their doubts, as Las Vegas is not known for its family-friendly atmosphere, while teenage son Rusty appears to be more enthusiastic.
