Fighting Back (1917)

Cashiered out of the army by what he believes was an unjust court-martial, the man known as The Weakling wanders aimlessly in the desert and is found by cowboys from the Lazy Y Ranch. They clean him up and give him a job on the ranch as a cowboy. He soon finds love with a local dance-hall girl, and discovers that his luck may be changing in more ways than one.
