Christmas Vacation

Clark Griswold (Chevy Chase) has a goal: the best Christmas ever for his family. He's planning a pool for the family as soon as his boss (Brian Doyle-Murray) comes through with his bonus and he's going to have the best light display in the neighborhood. Unfortunately, his whole family is coming for Christmas and when his wife's brother Randy shows up with his family, Christmas is going to get a whole lot more crowded at the Griswold house. Will the family survive or will they end up killing each other before Christmas morning?
