AAA can t help the roadside emergency that is the Johnson Family Vacation. Even the onboard navigation system has a meltdown on Nate Johnson (Cedric The Entertainer) and his family's cross-country trek to their annual family reunion/grudge match. Reluctantly along for the ride are Nate's wife (Williams), who s only in it for the kids; their rapper-wannabe son (Bow Wow); their teenage daughter (Solange Knowles) who s fashioned herself as the next Lolita; and their youngest (Gabby Soleil), whose imaginary dog Nate just can t seem to keep track of. Can the Johnsons survive each other and all the obstacles the road throws at them to make it to Caruthersville, Missouri? Can they find Missouri?
