From amazon.com:
Mattie Ross, a fourteen-year-old girl from Dardanelle, Arkansas, sets out to avenge her Daddy who was shot to death by a no-good outlaw. Mattie convinces one-eyed Rooster Cogburn, the meanest U.S. marshal in the land, to ride along with her. In True Grit, we have a true American classic, as young Mattie as vital as she is innocent outdickers and outmaneuvers the hard-bitten men of the trail in a legend that will last through the ages.
