The Sheriff of Medicine Bow (1948)

Monte Hale is a stagecoach driver for Jed Baker's stage-line. Jed believes his brother, Ralph, is behind the many hold-ups of his stagecoaches but has no proof. Ralph, in turn, blames Jed for the attacks on the linemen of his pioneer telegraph company. Big Bart, a ruthless gunman and outlaw-gang leader working for crooked banker Jordan Weatherbee, is actually behind the troubles of both companies. Bart plans to frame Jed for a double-murder and then kill him. Monte saves his life and, together, they devise a plan of their own to bring an end to the reign of lawlessness along the timber trail.

When an unscrupulous banker ruins his family, a young man swears to bring him to justice, so he adopts a new identity, the mysterious Judex, and ominously disguised and sunk into the muddy path of vengeance, punishes the crooks and protects the innocents. (Originally a twelve-part epic serial.)
