John Wheeler, a traction magnate, becomes heavily involved and is obliged to sell a large timber tract he owns in the Hudson Bay district. He owns the property jointly with Henri Corteau, and the deed is filed in the office of Magistrate Le Blanc, at Chalet. Bruce Mitchell, a wealthy young man about town, who is infatuated with Lois Wheeler, the madcap daughter of Wheeler, readily agrees to take over the property. In the northland the elder Corteau has died suddenly, and the Magistrate’s office, together with the Wheeler-Corteau deed, is destroyed by fire. The Magistrate receives word of the transfer between Wheeler and Mitchell and he sends for Jean Corteau, the son and heir of the late Henri Corteau, and asks him for the deed his father held, telling him he wishes to make a copy of it. When he adds that it is the only copy in existence, Jean walks out, saying he intends to keep the land himself. Meantime Mitchell has pressed his suit for the hand of Lois, and she takes a violent dislike to him. She resents it because he tries to make plain that her father is under obligations to him. Soon afterward Mitchell goes to Wheeler and wants to know why the deed has not arrived. Wheeler hopelessly shows him a letter from the Magistrate, telling of Jean’s action. Mitchell threatens to jail Wheeler, accusing him of obtaining money under false pretenses. Lois overhears the threat and also Mitchell’s offer to let the matter drop if Lois will marry him. Lois agrees to this proposal providing her father’s innocence cannot be proved. Lois goes to the northland and seeks out Jean. He will not see her, saying he will not have any dealings with women. The next day she sets out, dressed in boy’s clothes, on a dog sled for Jean’s home in the forest. Pierre, a guide, accompanies her. They arrive in sight of Jean’s cabin at nightfall, when Pierre attempts to force his attentions upon Lois. She flees and seeks refuge in Jean’s cabin, stumbling in his door in a faint. Later, she tells Jean she has become lest from a lumber camp, and asks if she may remain a while with him. He tells her he has always wanted a boy companion and helper, and that since she came like a “wounded snowbird” to his cabin, she may stay. Although Jean is brutal and primitive in many ways Lois soon finds he has a gentle nature. The next day Jean discovers Lois is a girl, when her fair falls out from under her cap. She confesses her identity and he is angry. But he consents to her remaining, and he fetches some of his mother’s clothes for her. Her one desire to get the deed is realized when she is dressing and finds the document hidden away behind a small mirror on the wall. That night she urges Jean to drink heavily, hoping to get away. He becomes fascinated with her and tells her he is going to save her father. He reaches for the deed and finds it gone. Her manner betrays Lois, and she confesses having the paper. Meanwhile Mitchell and Wheeler have come north in search of Lois. Pierre tells Mitchell she is living with Jean. In a jealous rage he goes to seek out Lois. He has Wheeler arrested and then sets out for Jean’s cabin. Arrived there he sarcastically accuses Lois of a common liaison with Jean. Jean demands that Mitchell apologize. He refuses and they fight. Both are seriously wounded. Mitchell staggers out of the cabin in the snow. Lois, left with the unconscious Jean, decides to steal the deed and leave. On the edge of a cliff Lois sees Mitchell fall to his death. Then a vision of Jean left alone in his helpless condition comes to her. She turns back and joins Jean. She nurses him back to strength and they go to the aid of Wheeler, intending to marry and live in New York. But after they are wed they hearken to the call of the north, and go back to the life where their love was born.
