Walker, Texas Ranger - Season 5 - Eps 12: The Deadliest Man Alive
The world's most deadly assassin who has left a trail of blood in history (and may even be involved in the JFK assassination), The Viper, is in town. Walker is informed and recruited by Interpol Agent Draper who's hunting the Viper now for nearly 25 years. Since the killer is in town to carry out another assassination - the target could be the visiting Israeli Ambassador - it's up to Walker to find and eliminate the Viper before he hits once again.

Synopsis
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.
