Anyone who’s ever piled into the car dreaming of a great vacation only to drive off into an out-of-control, disaster-prone, family-trip-gone-south will identify with this comedy. It’s a roadside emergency waiting to happen when Nate Johnson sets out with three unruly kids and one unsatisfied wife on a cross-country trek from California to Missouri for the Johnson family’s annual reunion/grudge match. Even if the Johnsons start out at each other’s throats, in the comic adventures ahead they’re about to rediscover one another’s hearts.
