The Lone Rider (1922)

When Ruth Harrison, daughter of wealthy cattleman Jud Harrison, sees a drifter trying to stop ranch foreman Bull Davidson from abusing a horse, she takes a liking to him and convinces her father to give him a job. However, Big Greeves, the leader of a gang of rustlers, decides to frame the drifter to divert attention from his own gang's rustling, and takes the drifter prisoner. Ruth finds out and attempts to save him. It turns out that the drifter may not be exactly who he says he is, and that Big Greeves may not be the actual boss of the rustler gang.
