The father of fourteen-year old Mattie Ross (Hailee Steinfeld) is murdered by hired hand Tom Chaney (Josh Brolin) while on a trip to Fort Smith, Arkansas to purchase horses. While collecting her father's body, Mattie asks the local sheriff about the search for Chaney. He tells her that Chaney has likely fled with "Lucky" Ned Pepper (Barry Pepper) and his gang into Indian Territory, where the sheriff has no authority, so she inquires about hiring a Deputy U.S. Marshal. The sheriff gives three recommendations, and Mattie chooses the "meanest" of the three, Rooster Cogburn (Jeff Bridges). Cogburn initially rebuffs her offer, doubting both her grit and her wealth, but she raises the money by aggressive horse-trading.
