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.
