Broncho Billy, a prospector, receives an offer of one hundred thousand dollars for his claim. The offer is overheard by Rundell, another prospector, and he proposes to sell his claim also. Broncho Billy hearing of this, plans a joke. He places gold in the blasting hole at Rundell's claim, and when the old prospector blasts he is so delighted at his good fortune that he falls dead from heart failure. Broncho Billy sends a note to Marguerite, Rundell's daughter, telling her the sad fate of her father, and realizing that he was the cause of all the sadness, changes the signs on the claims, she thinking that Broncho Billy's claim belonged to her father. He then notifies the Consolidated Mining Co. that he does not wish to sell. When he sees the girl's sweet face, he falls in love with her.
