Far away, in the timberlands of the North, where the purity of woman is placed above all else, lived Josephine Adare, a kind, honest soul, whose face plainly bore an expression of deep sorrow and anxiety. Up to this, God's Own Country, came a man, Philip Weyman, to spend a year in that region. The man meets the woman and falls in love with her. He begs her to confide in him her great sorrow, which he sees she is constantly thinking of, but she tells him that she cannot do so. Seeing that he is persistent, and really anxious to help her, she asks him if he would be willing to follow her wherever she goes, doing whatever she asks of him, asking no questions and with the hope of no reward but her undying gratitude. Owing to his great love for her, he consents, knowing that he will be working for a just cause. Through the long, bitter, northern winter, he travels with her, knowing neither where he is going nor what he is going to do. To aid her plans, they are married, but it is a marriage in name only. She then takes him to the home of her father, John Adare, a rugged woodsman, where she tells him to pose as the father of an infant which she shows him. For a moment, his faith in her wavers, when he sees the child, but his manhood conquers and he determines to stand by his promise. Then, on one eventful day the infant dies. After the baby's death Philip notices unusual activity about the camp, and suspects that Josephine's enemies are about. Though he knows not who they are, he longs to fight them, but Jean Croisset, Josephine's half-breed protector, who has also been assisting her in her trouble, tells him that he can do nothing but wait for orders from her. He is tempted to cast caution to the winds and search for them himself, but his better judgment prevails and he realizes that he must be satisfied with anxiety and inactivity. Josephine's ferocious wolf-hounds have grown to love Philip as they love their mistress. These terrible beasts, though born for fighting, have big hearts in their savage breasts, and at a word from one whom they love, would tear an enemy to pieces. One day, Josephine, who is known throughout the neighborhood for her kindness and love of children, is called to another village to tend a sick child. Jean follows to protect her, and Philip trails him with the dogs. Philip learns that she was kidnapped by Lang, who, Jean tells him, is responsible for all her troubles. Philip rouses all the honest woodsmen in the neighborhood, who love Josephine for her kindness, and they set out to rescue her. They also enlist the aid of a tribe of Indians in their cause. After traveling for some time, the rescue party traps the villainous gang in its lair, "Devil's Nest." Here Lang and his gang barricade the doors and windows and prepare for the attack. A battle ensues, and Lang's followers, seeing they are being beaten, try to escape but find themselves hemmed in. In the midst of the battle, Jean is shot, and, knowing he is about to die, calls Philip to his side. He tells him how, a year before, Josephine's mother had fallen into Lang's clutches while her husband was away, and of the birth of the child, which Josephine had claimed as her own to shield her mother's honor. The story told, the faithful half-breed dies, with a parting injunction to Philip to kill Lang and destroy the incriminating papers in his possession. During a lull in the fighting, Lang tries to escape through a window with Josephine. His action is seen by Philip, who rushes over to protect her. In the struggle which follows, Lang manages to gain the upper hand, and reaches for his knife to end Philip's life. Seeing his danger, Josephine releases the dogs, with a command to kill. As though they knew the sorrows of their mistress, the shaggy beasts leap upon the struggling forms, single out Lang and kill him with their merciless fangs. Philip informs her that he knows all, and that she need no longer fear for her mother's honor, as he has destroyed the papers. She tells him that she has always loved him, and Philip looks forward to a happy future, in God's country with the woman of his choice.
