Hot Pursuit (2015)

Rose Cooper (Reese Witherspoon) is an uptight and by-the-book cop whose name has become synonymous with screw-ups. She's given a chance to redeem herself one day when she is assigned to protect a federal witness, Daniella Riva (Sofia Vergara), 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. However, their greatest obstacle to making this out alive may be themselves as they learn that Cooper has now been considered a fugitive fleeing with Daniella.
