The Westward Trail.

Ann and Tom Howard arrive from the east to take up ranching. But Tom wants to return and forges his sister's name to the deed and sells it to Larson. Eddie knows there is silver ore in the area and that Lawson, who killed the Sheriff, is out to get all the ranches. When Lawson appoints himself the new Sheriff, Eddie organizes the ranchers to fight Lawson and his men.
