Johnson Family Vacation (2004)

Even A.A.A. can't help the Johnson family on this roadtrip for Nate Johnson and his family who embark on a cross-country trek to their annual family reunion/grudge match. Reluctantly along for the ride are Nate's wife, who's only in it for the kids; their rapper-wannabe son; their teenage daughter, who's fashioned herself as the next Lolita; and their youngest, whose has an imaginary dog that Nate just can't seem to keep track of, no matter how he tries. Can the Johnsons survive each other and all the obstacles that the road throws at them, to make it to Caruthersville, Missouri? Can they even find Missouri?
