the story of Mattie Ross, who is just fourteen years of age when a coward going by the name of Tom Chaney shoots her father down in Fort Smith, Arkansas, and robs him of his life, his horse, and $150 in cash money. Mattie leaves home to avenge her father's blood. With the one-eyed Rooster Cogburn, the meanest available U.S. Marshal, by her side, Mattie pursues the homicide into Indian Territory.
