Chevy Chase ("Caddyshack," "Funny Farm"), Randy Quaid ("The Adventures of Pluto Nash," "Independence Day") and Beverly D'Angelo ("Summer Catch") return in the fourth installment of the blockbuster "Vacation" series. With Dad's prompting, the Griswold family reluctantly hits the road for another hilarious vacation, this time to the glitzy mecca of Elvis-impersonators, slot machines and showgirls: Las Vegas. Plans to renew their wedding vows take a slight detour when Vegas veteran Wayne Newton shows more than a casual interest in Mrs. Griswold! "Chase is a perfect blend of out-of-control compulsiveness, while D'Angelo is winningly radiant as his sweet-and-saucy wife." -- The Hollywood Reporter.
