Monsters are running amok in Houston--Monster trucks, that is. The Holden's are asked to help a family friend by chasing down a Monster Truck, which has been stolen by a man with a hair-trigger temper. Meanwhile, the In-laws, Chad and Michael, go head to head against their archrivals, the Big Texans, Marshall and Korchenko. The two teams are trying to be the first to find a missing truck containing high-end consumer electronics and, most importantly, the truck's driver whom they fear is the victim of foul play.
