Tim Allen, John Travolta, Martin Lawrence and William H. Macy -- hit the road in this rollicking comedy-adventure about a group of middle-aged friends who decide to rev up their routine suburban lives with a freewheeling motorcycle trip. When this mis-matched foursome, who clearly have grown far more used to the couch than the saddle, set out for a once-in-a-lifetime experience - they encounter a world that holds far more than they ever bargained for.
