Texas Ranger Cordell Walker is one of the last old-fashioned heroes of the West. He is a protective friend, but a relentless foe who will stop at nothing to bring a criminal to justice. Walker draws on the traditions of his Native American heritage and works mostly on instinct. James Trivette is his partner who has a more modern approach to crime-solving. Retired Ranger C.D. Parker and county assistant district attorney Alex Cahill support the Rangers in their battle to serve justice.
