When Men Are Tempted (1917)

College friends John Burt and Arthur Morris are rivals for the hand of Jessie Garden. They come to blows over Jessie, and John, believing that he has killed Arthur in the fight, goes West to search for the location of a mine belonging to his grandfather. John finds the mine and returns home a millionaire, but discovers that Jessie is planning upon sacrificing herself to Arthur in order to retrieve the fortune her father lost as a result of Arthur's stock manipulations. John puts his own fortune at Garden's disposal and succeeds in breaking Arthur. In anger and hatred, Arthur attempts to kill John but fails and commits suicide instead. With the menace of Arthur removed, John and Jessie marry and face a happy life together.
