Uptight and straight-laced, FBI Special Agent Sarah Ashburn is a methodical investigator with a reputation for excellence — and hyper-arrogance. Shannon Mullins, one of Boston Police Department’s “finest,” is foul-mouthed and has a very short fuse, and uses her gut instinct and street smarts to catch the most elusive criminals.

Neither has ever had a partner, or a friend for that matter. When these two wildly incompatible law officers join forces to bring down a ruthless drug lord, they become the last thing anyone expected: buddies. From Paul Feig, the director of “Bridesmaids.”Director: Paul Feig. Cast: Sandra Bullock, Melissa McCarthy, Demián Bichir, Marlon Wayans, Michael Rapaport. Rated: R. Time: 1:57.
