WALKER, TEXAS RANGER is an action-drama about modern-day Texas Ranger Cordell Walker, whose independent crime-solving methods have their roots in the rugged traditions of the Old West. Walker's closest friend is a former Texas Ranger, C. D. Parker, who begrudgingly retired after a disabling knee injury but continues to help Walker, occasionally offering advice on difficult cases. Parker now owns "C. D.'s," a saloon-restaurant with country music and dancing. Assisting Walker is Ranger James Trivette, a philosophical ex-football player, originally from the Baltimore projects, who represents the new breed of law-enforcement officer who bases his crime-solving on reason and modern-day tools such as computers. Alex Cahill is the county assistant district attorney, who shares a mutual attraction with Walker while often disagreeing with his unorthodox approach to law enforcement.
