Where Trails End

U.S. Marshal Tom Kenyon (Tom Keene), with his sidekick pal Pierre La Faire (Frank Yaconelli) is sent to aid the valley ranchers who are being driven from their homes by a gang of terrorists. Tungsten has been secretly discovered and enemy agents led by Tip Wallace (William von Brincken using his WWII hide-out alias of William Vaughn) in cahoots with Jim Regan (Charles King), crooked foreman of the Allen (Steve Clark) ranch. Tom trails Regan to the gang's hideout and sends the recently-orphaned Donny (Donald Stewart) for the sheriff.
