The Jordans, Phil and Ruth, accompanied by Philip's wife, Polly, and Dr. Winthrop Newbury, a suitor for Ruth's hand, bid old Mrs. Jordan good-bye at the station of Milford Corners, Mass., and depart for the west, to work over some unredeemed desert land, which was left to the Jordans by their dead father. Arriving in the west, they take up their work, but it proves anything but a success. On the brink of the Great Divide lives Stephen Ghent, an untamed and untrained man of the west, and on account of his manner is respected by the habitués of Miller's saloon and dance hall in the town, which he and two of his acquaintances in the persons of Pedro, a half-breed Mexican, and Dutch, a brutal type of the west, frequent. Polly tires of western life and jumps at the chance to take a trip to Frisco. Philip drives her down to the station that night. On an adjoining ranch a cowpuncher is seriously hurt and a boy is dispatched for Dr. Newbury. After cautioning Ruth to retire early, the doctor takes his leave. Stephen Ghent, Pedro, and Dutch are down in the town drinking. They afterward depart and start up the Coldwater Trail, which runs alongside of the Jordan home. As they pass the dimly lighted cabin, they see a woman standing in the doorway. Cautiously approaching the door, they enter the cabin and Ruth is overpowered. Dutch and Ghent fight a duel for her in which Dutch is killed. Pedro is bought off by Ghent with a string of nuggets, and Ruth belongs to him. In the man of the woods, Ruth recognizes the ideal man she desires for a helpmate. Ruth agrees to marry Ghent and live as his wife in name only until he has changed his character. Ghent agrees and they are married. Ghent then brings her to his cabin. As day by day goes by, Ruth begins to see other qualities in her husband and also to believe in him. One night, however, Ghent filled with a desire for her and goaded on by the whiskey that is in him breaks his promise. Ruth denounces him for his actions and tells him that not until he has purged himself through suffering will she ever believe in him again. She also tells him that she is going to earn enough money to buy back the string of nuggets from Pedro, with which he managed to get her into his power. Some time later Ruth departs for town to sell her last blanket. She has been weaving Navajo blankets in order to raise the necessary amount to buy back the nuggets. In the meantime the Jordans become disgusted and prepare to go back east. While waiting at the station they find Ruth, who has just completed the sale of her blanket. They see her start up the trail and follow her on foot. Ruth buys back the string of nuggets from Pedro, but she has not time to turn it over to Ghent upon her arrival at the cabin before she is overtaken by the others. It is her desire to have them believe she is happy and refuses to go back east with them. She introduces Ghent to them just as they are ready to catch the train. Ghent, unable to understand her changed attitude, starts to thank her. She tells him that circumstances forced her to act as she did, but that she is now able to buy back her freedom from him. Ghent is stunned, and at first refuses to let her go, but when she tells him of the life that is to come and that it is their duty to protect its happiness through a mother's love, he finally releases her from her promise, and Ruth, with the sense of newfound freedom, starts down the trail to overtake the others before it is too late. Ghent's attention as he looks after her is suddenly attracted to a bit of trembling earth on the mountainside. He realizes the great danger that Ruth is in and starts down the trail to rescue her. He is just in time and has thrown her to one side when the landslide comes upon him and carries him into the valley below. The rumbling sound has caused the others to look back. A reunion takes place over the injured Ghent. He is brought to the cabin, where he recovers under the care and attention of Dr. Newbury and Ruth. Ruth tells him that he has purged himself through his suffering and once more the couple start out in life upon a happier basis.
