Henry Sherwin has every cent invested in a mine which is apparently valueless. James Fleming, a mine expert, discovers a rich vein of gold in the mine but keeps it secret. Mr. Sherwin dies and leaves Betty, his daughter, in the care of John Kenwood and his sister, Constance who, finding the estate worthless, allows Betty to believe she has an income. She goes to boarding school, lives luxuriously, and when she returns home is shocked to find John and Constance working, so she hires two servants. A frost wipes out the orange crop, their last hope. Fleming proposes to Betty and is refused. Betty tells John he may have all her money, and although heartbroken and discouraged, he is greatly amused. Fleming finally tells Betty her mine is worthless, again asks her to marry him and is again refused. Betty dreams she sees gold pouring from her mine and runs away. Going to the mine she finds Big Jim, and together they search for gold. The boys "salt" the mine and Betty is delighted at her supposed find of gold. She learns of the joke and decides to try her luck at gambling. She stakes her nuggets in a roulette game and loses. Fleming finds her here and takes her in his arms, announcing, just as Kenwood enters, she is to become his wife. As Jim and the proprietor of the gambling house are looking over the nuggets Jim notices a strange one and asks Betty where she found it. She leads him to the mine and he discovers a rich vein, worth a million. Fleming's conspiracy is discovered. John takes Betty in his arms and tells her he has always loved her, and is informed of the discovery of the gold. Her sudden wealth seems in his mind to create a great gulf between them, but she wriggles back into his embrace. She tells him she loves him and asks him to be her husband. He takes her closer in his arms and their happiness is complete.
