Watch True Grit

When Frank Ross is murdered by his hired hand, Tom Chaney, Frank's tomboy teenage daughter, Mattie, is determined to avenge his death. She sets out from Delaney, Arkansas to Fort Smith, Arkansas to hire U.S. Marshall Rooster Cogburn to help her hunt down Chaney. Rooster Cogburn is known for his tough reputation of getting the job done. Mattie says he has "true grit." Rooster is also a one-eyed, pot-bellied, drunken, hard-nosed old Marshall. The two set out and are soon joined by Texas Ranger, LaBoeuf, who is hunting Chaney for killing a Texas Senator.

Chaney has joined up with a band of outlaws headed up by Ned Pepper who is hiding deep in Indian Nation Territory, that became Oklahoma. To make matters more complicated, Chaney's boisterous buddies, Ned Pepper, Quincy, and Moon have no qualms about killing the strong-willed teenager that is causing them trouble.

Mattie is caught by Chaney when she slips down a steep hill and comes face to face with the outlaw. She shoots and wounds him, but Pepper and his gang capture her, causing Cogburn and LaBoeuf to leave without her. Cogburn doubles back and attacks Pepper's gang as LaBoeuf finds Mattie and takes her and Chaney to a safe place.

Cogburn fatally shoots three of the gang members and wounds Pepper. However,not before Pepper shoots Cogburn's horse, leaving Rooster trapped underneath. Pepper is about to finish off the helpless Marshall, when LaBoeuf shoots Pepper from an outcropping and kills him.

When LaBoeuf and Mattie return to Pepper's camp, Chaney comes out from his hiding place and strikes LaBoeuf with a rock, rendering him unconscious. Mattie shoots Chaney in the arm, but the recoil from the gun knocks her into a pit, breaking her arm. Cogburn rides in and kills Pepper, knocking him into the same pit. Mattie is bitten by a rattlesnake and Rooster descends into the pit to rescue her.
