Frontier Law

Riding south from Montana, Jim Warren and his friend, Ramblin' Rufe, discover that Jim's old pal, Dusty Norton, is working for triggerman Joe Hawkins. Later, Jim and Rufe see cattleman Frank Rodgers kill cattleman Farrell in self defense, after a dispute about the illegal grazing of Farrell's stock on Rodgers' land. The only other witness is Lois, Rodgers' daughter. Rodgers is jailed, and Hawkins, who has also been stealing cattle from both ranches and altering the brands, tries to incite a lynching. Hawkins causes a confrontation between Jim and Dusty that leads to a climatic gun battle with the two old pals against the Hawkins gang.
