Outlaws of Boulder Pass

Gunslinger Ned Harkness murders his partner, Jeff Hammer, to gain control of the Bar Bee X Ranch and Boulder Pass. Enforcing a huge tariff for use of the canyon trail, Harkness bleeds neighboring ranchers dry. Cowpokes have no choice but to pay to use Boulder Pass so as to avoid driving their herds to auction through a deadly, parched desert. (official distributor synopsis)
