National Lampoon's Vegas Vacation

Synopsis

The Griswald family, led by Clark (Chevy Chase), are off to Las Vegas for the holiday of a lifetime. Unfortunately Clark is soon transformed into a compulsive gambler, daughter Audrey becomes an exotic dancer, and son Rusty begins posing as a suave high roller. Will Clark's wife Ellen (Beverly d'Angelo) forgive him his flaws and reunite the family? It's hardly a safe bet.
