Blue Canadian Rockies.

Montana ranch owner Cyrus Bigbee sends his foreman, Gene Autry, and Rawhide Buttram to his Canadian timber land to stop the marriage of his daughter Sandy to Todd Markey, whom he dislikes. Sandy wants to turn the property into a dude ranch, with Carolina Cotton and the Cass County Boys (Fred S. Martin, Jerry Scoggins and Bert Dodson) among the entertainers, and runs up against local timbermen who want it for cutting timber. When a Mountie is murdered, with suspicion pointing to Todd, Gene finds the real culprit and brings peace to the area.
