Viviette, the impulsive and coquettish adopted daughter of wealthy Englishwoman Mrs. Ware, completes her education and returns to her mother’s country estate. Young Dick Ware, who is as impulsive as Viviette, falls passionately in love with the girl, and although she is attracted to him, his lack of ambition causes her to conceal her affections. When Dick’s sober and successful brother Austin takes leave from his London law practice to visit his family, Viviette befriends him, and the two secretly make plans to secure Dick a position in Vancouver. Although Austin loves Kathryn Holroyd, Dick believes that Austin is in love with Viviette, so when the latter jokingly suggests that the brothers fight a duel over her, Dick takes the idea seriously. He nearly kills Austin, whereupon Viviette, realizing the gravity of the situation, offers to accompany Dick to Vancouver as his wife.
