Academy Award winner Reese Witherspoon is Officer Cooper, an uptight and by-the-book cop trying to protect a federal witness, Daniella Riva, the vivacious and outgoing widow of a drug boss. As the two polar opposites race through Texas, they find themselves pursued by everyone from crooked cops to murderous gunmen. But their greatest obstacle to making it out alive may be themselves, in this high-action, high-hilarity road-trip comedy.
