Mark Reid, a young prospector, discovers gold in the Sierra foothills. He meets an old man known as "The Good Samaritan," who counsels him and welcomes him into his home. While he is away registering his claim, another prospector, Mike O'Hara, comes along, and, seeing no one around, takes possession of the gold mine. When Reid returns, the two engage in a struggle. As Reid is about to be overcome, an Indian slips a dagger into his hand. Reid is about to stab O'Hara when The Good Samaritan appears and stops the fight. Reid and the O'Hara set aside their differences and decide to become partners.
