All Mitch Snider wants for his family is a traditional holiday feast with the relatives. The problem is that he doesn't have any. That is until he gets an invitation in the mail from his long-lost cousin Woodrow. What follows is a full-course meal of nonstop laughs when the neurotic suburbanites clash with the hippy hicks from hell in National Lampoon's most outrageous family misadventure yet.
