The Fighting Peacemaker.

Peace River Parker, foreman of the Cross L Ranch and engaged to Jess, the daughter of the owner, is railroaded into a prison term by the false witness of Jefferson Crane, who covets the ranch and Jess. Through the complicity of Clell Danert, a villainous foreman who also desires Jess, Crane arranges to ruin the Marshall ranch by driving a herd of sheep onto the cattle range.
