Bob, a young rancher, buys a mine on his leased land to prevent the working of it. However, surveys show a valuable mineral deposit, so he and Carol, the granddaughter of the discoverer of the mine, who has been forced to sell it to a crook, start operations on it. Fawcett, the crook, schemes to get the mine back, but is outwitted at every turn and loses his life in the dynamiting which he inspired.
