Fourteen-year-old hires a marshal for vengeance
After drifter Tom Chaney shoots her father in Fort Smith, Arkansas, and flees into Indian Territory, 14-year-old Mattie Ross first bargains back money from horse trader Stonehill. She then hires one-eyed, hard-drinking U.S. Marshal Rooster Cogburn because she is told he has 'grit,' and rides with him and Texas Ranger LaBoeuf. She shoots Chaney herself, and the recoil knocks her into a snake pit where a rattlesnake bite costs her an arm. Cogburn rides her pony to death getting her to help, and she lives the rest of her life as an unmarried, one-armed businesswoman.
