Plot Summary:Bruce Andrews, a mining engineer, who owns a sheep ranch in a copper-rich region of the Northwest, marries Isabel Hollins, a vacationing Easterner. Isabel is also loved by Burton Mortimer, the partner of Bruce's neighbor, Edmund Rawn, an unscrupulous mine owner. Rawn makes Bruce a lucrative offer to investigate copper property in Chile so that he can gain control of Bruce's land. An explosion of dynamite set off at Rawn's request in the Chilean mine causes Bruce to lose his mind. While a Chilean shepherd and his daughter care for him, Isabel is told that he died. After Mortimer and Rawn surreptitiously ruin Isabel financially, she marries Mortimer to provide for her young son, and sells the ranch to Rawn. When Bruce recovers his senses and returns, Mortimer tells him about the marriage and claims that the child is his. Bruce leaves, but after learning the truth, he ruins Mortimer and Rawn on the stock market. After Mortimer kills himself, Bruce and Isabel are reunited.
