Lonnie Earl (Thornton) is a self-centered Little Rock, Arkansas car dealer who is married to Darlene (Richardson). Lonnie is looking for a little excitement, so together with his dimwitted best friend Roy (Swayze) and Roy's wife Candy (Theron), the foursome decide to make a trip to Reno, Nevada for a monster truck extravaganza. They grab a fully loaded S.U.V. from Lonnie's lot, fill up the cooler with Pabst Blue Ribbon, and hit the road. However, what initially begins as a fun-loving good time for the seemingly happy married couples quickly takes a turn for the worse. While newlyweds Candy and Roy are desperately trying to get pregnant, it occurs to the group that Candy might already be pregnant--with Lonnie's baby. Together Thornton, Swayze, Richardson, and Theron are riotously funny in this down-home comedy made all the more poignant with its big hair, snakeskin boots, and backwater accents.
