True Grit tells the story of Mattie Ross, who is just fourteen when the coward Tom Chaney shoots her father in Fort Smith, Arkansas, and robs him of his life, his horse, and $150 cash. Filled with an unwavering urge to avenge her father’s blood, Mattie enlists one-eyed Rooster Cogburn, the meanest available US Marshal, as her partner in pursuit, and they head off into Indian Territory after the killer.
