When accomplished businessman Steve (Bob Poole) meets ambitious medical student Tina (Kim Kilway), who's half his age, he's immediately smitten. Tina seems to enjoy Steve's company as well, though she's already dating a pathologist named Jack (James Hansen Prince), who's closer to her age. What starts out as an innocent love triangle turns dangerous when jealousy, passion and undeniable attraction collide to complicate matters.

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.
