South of northern lights (1922)

Falsely accused of murder by a gang that wants to obtain possession of his ranch (on which gold has been discovered) northwestern rancher Jack Hampton flees across the border into Canada pursued by the Northwest Mounted Police and an American sheriff. Chick Rawlins, the gang's leader, runs a place at a trading post, and the Canadian authorities have sent Jane Wilson into the camp to get evidence against him. Captured by the crooks, she has been imprisoned in the mountains. Her escape develops into a long chase by the crooks, Hampton, and his pursuers.
