Walker always seems to be just one step behind a vigilante, who gets the jump on the men Walker's supposed to arrest and takes the law into his own hands.

A 6-year-old boy is mortally wounded during a late-night shootout in a residential neighborhood between the Rangers and two criminals; Trivette was involved in the shootout when the boy became caught in the crossfire. Initial findings implicate a woefully remorseful Trivette, who is suspended as the whole incident is being investigated. As he suffers greatly, he must contend with an overzealous investigating officer who wants to convict Trivette and have him removed from the Rangers (the officer had been passed over in favor of Trivette when both were up for being named Ranger) and a careless TV news reporter who constantly and errantly states on the air that the boy was shot as the result of carelessness on Trivette's part. As Walker seeks to uncover the truth, he and Alex help comfort the parents of the boy and pray for a miracle.

Walker y su equipo todavía están buscando al hombre que está eliminando a agentes encubiertos. Obtienen una pista cuando el hijo de un mafioso se acerca a las personas que pagan a su padre por protección y les pide más dinero. Cuando uno de ellos decide ir a su padre y contarle lo que está haciendo, él lo mata. Alguien lo presencia y se lo cuenta a Walker. Entonces, Walker se dispone a atrapar al hijo del mafioso. El mafioso luego va al presidente para resolver este asunto.
