Ace of the Saddle is a 1919 American silent Western film directed by John Ford and featuring Harry Carey.

After the Yucca sheriff (Harris) refuses to help stop the cattle rustling, he goes to Pinkerton Sheriff Faulkner (Lee), who is unable to help him because he lives in Yucca County.

While Yucca County may be lawless, no man may be shot unless he is armed, so the Yucca sheriff devises a scheme place an unloaded gun in Harry's hands and then have him killed.

Harry sees through the ruse and uses the sheriff's gun to kill two men before they can shoot him.

Before the rustlers can be hanged, the Yucca sheriff frees them and also kidnaps Madeline.
