The Law of the Great Northwest (1918)

Hal Sinclair, the chief agent at the Fort Roscher trading post in the Canadian Northwest, controls the town and cheats the trappers, until a group of independent fur traders arrives. After nearly all of the traders are killed by Sinclair's brutal henchman, Mont Brennan, Officer Jamison of the North West Mounted Police is sent to investigate. Charles Morin, a wealthy French Canadian businessman, also arrives at Fort Roscher that week with the intention of entering the fur trade, and soon falls in love with Petain Monest's pretty daughter Marie. Sinclair, who also loves Marie, commissions Brennan to kill the young trader, but Marie overhears their plans. As Brennan is taking aim, Marie shoots and kills him and subsequently is accused of murder. Jamison has also fallen in love with Marie, but realizing that she prefers Morin, he decides to stand by the young couple. With Jamison's help, Marie is exonerated and finally joined to the man whose life she saved.
