Jessie Thornton, the beautiful only child of Eathen Thornton, one of the richest most powerful men in the state of Montana, has never heard the word "no" until she sets her sights on Two Spirits, a young Blackfeet Indian her father has hired onto the ranch to tame the wild mustangs brought down out of the hills. Jessie soon finds herself fighting an uphill battle against 1903 Montana morals and small-town bigotry in her struggle to be with the man she loves.
