Dance-hall girl Colette Brissac, brought up in the Canadian Northwest, refuses the protection of New Yorker Lucky Folsom, who later marries Gloria Waldron, an ambitious woman actually in love with engineer Martin Bates. When Bates drifts into the mining town, the miners, while drunk, force him to marry Colette. She nurses him back to health and they gradually fall in love. The arrival of Folsom and Gloria threatens to break up their marriage, and Colette prevents a fight between the two men by wounding Folsom, causing the latter to come to his senses and teaching his wife a lesson.
