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.

Asthmatic teenager Barry Gabrewski is a daydreamer.

With help from his teacher's wise old uncle, Mr. Lee, Barry learns the finer points of martial arts and enters a karate championship.
