Modern-day Texas Ranger, Cordell Walker's independent crime-solving methods have their roots in the rugged traditions of the Old West.
Walker's closest friend is former Ranger, C.D. Parker, who retired after a knee injury, and now owns "C.D.'s," a Country/Western saloon/restaurant.
Rookie Ranger, James "Jimmy" Trivette is an ex-football player who bases his crime-solving methods on reason and uses computers and cellular phones.
Alex Cahill is the Assistant DA who shares a mutual attraction with Walker, but often disagrees with his unorthodox approach to law enforcement.
