A Knight of the Range (1916)

Unaware of the weakness of Bob Graham's character, Bess Dawson decides to marry him instead of the other cowboy who loves her, Cheyenne Harry. Before the wedding, however, some crooks induce Bob to take part in a hold-up. Then when Harry hears that a posse has been dispatched to catch Bob, he rides out to him and helps him escape. Determined to spare Bess from marrying a convicted criminal, Harry then lets the posse think that he himself, and not Bob, was involved in the robbery. Bess is horrified that Bob has let Harry take the blame and finally realizes that she picked the wrong cowboy. As a result, after Bob is killed in a gunfight and Harry has been cleared of the robbery charge, she quickly accepts his marriage proposal.
