Shadow Ranch (1930)

Summoned by his friend Ranny Williams (Frank Rice), Sim Baldwin (Buck Jones) rides to the aid of Circle O Ranch owner Ruth Cameron (Marguerite De La Motte), who is under pressure to sell out to Dan Blake (Albert J. Smith), who wants control of a dam on the ranch that is central to the town water supply. Sim arrives to find that Ranny has been ambushed; vowing to avenge the murder of his old friend, Sim takes up Ruth's fight and incurs Blake's enmity. Blake begins to rustle the ranch cattle but Sim lays a trap and captures several of the rustlers and marches them pantsless into town. Blake threatens Sim with a showdown unless he leaves town. Fat chance.
