The Gunfighter.

Billy Buell (William Farnum), a stranger involving himself with a long-standing mountain feud. The Benchleys and the Camps have been feuding ever since Lew Camp (J. Morris Foster) learned that his daughter Nellie (Doris May) was stolen by Jacob Benchley (Arthur Morrison) to replace a dead Benchley baby. Buell, who has fallen in love with Nellie, returns her to her mother (Virginia True Boardman). That doesn't sit well with the Benchley clan, who arrive for a final shootout.
