Grace is a street racer on the highway whose car follows... people. Arthur is a policeman who tries to make a better world every day. They launch into a race together, an event from Los Angeles to Phoenix in which the loser loses his life. Along the way they meet psychopaths, monsters and innocents. Arthur wants to do the right thing, but the rules don't allow his moral code to exist. Grace finally convinces Arthur, it's a do or die race. They must unite or lose their lives. Will they end up lasting only to die? Will Grace do anything to win? Who fuels the car afterwards?
