Elias Henders is the prosperous owner of a ranch and a gold mine. Competing for his daughter Diana, ranch hand Colby sabotages recovering alcoholic foreman Bull, and takes his job. The local stage is repeatedly robbed of gold bullion from the owner's mine, and Bull is suspected. The cowardly sheriff does not take action on the robberies. Rich Easterner Wainwright tries to buy the mine and ranch for a low price, but Henders refuses the offer and discusses the property's true value with Diana. She is intrigued by Wainwright's Eastern-educated son Jefferson, who proposes marriage. However, when they are attacked by Indians during the roundup, he runs rather than defend her. Henders is mortally wounded in the battle. Henders will bequeaths his property to his brother John back East so that he can take care of Diana, but John dies too. The Wainwrights pretend that Henders had agreed to a sale, but Diana knows better. Diana's Eastern cousin Lillian brings Corson, a lawyer, to try to seize the ranch and gold mine. They insist that the ranch and mine are nearly played out, and that they should sell the property, offering her a small amount. They show their ignorance about western ways. Bull encourages Diana that the property is worth more than they say, and advises her that the Wainwrights are often at the mine. The Eastern lawyer finally announces that Diana has no property rights due to the wills.
