The Toughest Gun in Tombstone, at least according to this film, as Arizona ranger Matt Sloane (George Montgomery). Working undercover, Sloane infiltrates an all-star outlaw gang consisting of Johnny Ringo (Jim Davis), Ike Clanton (Gerald Milton), Curly Bill Broces (Lane Bradford) and several other sagebrush celebrities. His purpose: to put an end to the smuggling of silver bullion across the Mexican border. Complicating matters is Sloane's concern over his young son Terry (Scott Morrow), who is being pursued across the territory by the man who murdered Sloane's wife. Not exactly an "A" picture, Toughest Gun in Tombstone is too well-mounted to be dismissed as a "B."
