A Man from Nowhere (1920)

Clay Norton and Duke Fuller are partners in a mining venture and have several claims, none of which have proved particularly successfully but do have promise. They are both in love with Agnes, and Clay wins her hand. While he is away in a nearby town to buy a wedding ring, Jim Butts, who has the territory's best mine, dies and Duke jumps his claim and sells it for $10,000, and the widow Butts is left penniless. When Clay, on his return, finds out what Duke has done, he demands his partnership share of $5,000 and tells Duke that they should see the widow and give her the money to go East so she will cause them no trouble. They visit her together and Clay tells her he will give her $5,000 and forces Duke to do the same. Overcome with the shock of the good fortune, the widow faints, and Duke, furious at being tricked, rushes from the cabin and meets Agnes, who is on her way to meet Clay. He takes her to the door of the cabin where she sees the widow Butts in the arms of her sweetheart. Misunderstanding the situation and being told by Duke that Clay is unfaithful to her, she breaks off their engagement.
