Through circumstantial evidence, Yvonne Desmarest is branded by Judge Duroacher as the "other woman" in a sensational murder case. She retreats to her father's hunting lodge near Hudson Bay, Canada, where she meets Scarborough, an Indian girl, and Émile (an old trapper who becomes her protector). Realizing his error, Duroacher follows Yvonne, thus precipitating a series of events in which the judge is suspected of murdering Scarborough, and Émile injures Duroacher out of jealousy. Yvonne's name is cleared, as is that of Émile, who has been sought for many years on a murder charge. Yvonne and Duroacher realize their love for each other.

""You! You know I am innocent! Yet you let them brand me! But I shall live to see you dragged in the mire as you have dragged me""
