 In this spinoff of Walker: Texas Ranger, Detective Carlos Sandoval resigns from the Dallas Police after his partner is murdered. He then hooks up with childhood chum Trent Malloy, an ex-military martial arts instructor. Together they decide to form a private investigation business. Trent s brother, Tommy, and ex-cop turned bartender Butch McMahon help them out from time to time. The cynical Detective Ryan fills the Inspector Lestrade role. Sometimes this show delves into darker territory than its predecessor.
