Clark Griswold, head of the Griswold family, has vowed to stay home with his loved ones this year and enjoy a peaceful Christmas. But peace is the last thing they get: the Griswolds’ roof is decked out with 25,000 lights and looks like an airport runway. The search for the perfect Christmas tree turns into a nightmare. Then the relatives descend, the Christmas turkey explodes on the dining table, and a SWAT team surrounds the house. Chevy Chase, Beverly D’Angelo, Randy Quaid, Juliette Lewis and others turn every holiday tradition upside down in this irreverent comedy.
