Blue Canadian Rockies

In northern Montana, wealthy rancher Cyrus Higbee asks his foreman, Gene Autry, and Gene's friend, Rawhide Buttram, to travel to Canada to the Higbee Lodge, which his daughter Sandy is attempting to turn into a dude ranch and protect from logging, despite Cyrus' orders to the contrary. Cyrus suspects that Sandy's business partner, Todd Markley, is courting her to gain control of the business and has arranged a job for Gene, hoping he will break up his daughter's romance. After Gene and Rawhide arrive in Canada, Rawhide's attempt to shoot a moose attracts the attention of Sandy and her foreman, Pop Phillips. Pop recognizes Gene as the new addition to the Cass County Boys, the lodge's singing act. As the group talks, a pickup truck driven by lumbermen Swede and Frenchy races recklessly at them and Gene gives chase on his horse. Resentful of anyone associated with the Higbee Lodge, which has put their mill out of business, Swede and Frenchy attack Gene, but the fight is broken up by the head of the mill, Ed Mitchell. Sandy rides up and demands that Mitchell and his men maintain their agreement not to interfere with their guests and cease using the Higbee road. At the lodge, Sandy introduces Gene to Markley who regards Gene with jealousy before confiscating his gun as part of the rules of the lodge. Later, Pop confides to Gene that as Cyrus' former partner, he is disappointed in Sandy's association with Markley and her determination to change the lodge. At the lodge's gala opening, singer Carolina Cotton performs, then Gene and Rawhide are forced to cover for the delayed Cass County Boys, raising Sandy's and Markley's suspicions. Carolina investigates Gene's belongings and discovers the Higbee brand on Gene's horse and informs Markley, who wonders if Gene has been sent by Cyrus. Shortly afterward, someone releases the horses, and Markley is found dazed just outside the paddock. Gene chases the culprit, who abandons his horse and flees in a Mitchell company truck. Gene retrieves the horse and notices Pop's saddle on its back. When confronted in his room, however, Pop mentions that he saw Markley hanging around the paddock. The next day Gene and Sandy round up the stray horses, and near the lumber mill, Gene is nearly struck by a falling tree. Shots ring out and, unarmed, Gene and Sandy are forced to flee. They run into Markley, who is holding a gun he claims he found on the trail. Back at the lodge, Gene reports the gun registration number to Mountie headquarters in hopes of tracing its owner. That night during a masquerade party for the guests, Cyrus slips in, hoping to be undetected. Sandy discovers her father, however, and he pleads with her not to marry Markley, who grows angry. The party is broken up by the discovery of a dead Mountie, clutching a note for Gene that identifies the gun as Mitchell's. Markley immediately goes to the mill to accuse Mitchell and is attacked by the lumbermen until Gene comes to his rescue. When Gene and Markley depart, Mitchell and his men arm themselves and follow. Rushing to the lodge, Gene demands that Sandy return their guns so they can defend themselves, but they discover the storage trunk is empty. Gene places a call for help to the Mounties, whom he had asked Pop to call earlier, but they claim they never received a summons. Markley packs to leave, admitting to Sandy that he had designs on the property, but that he cannot endure her suspicions of him. Meanwhile, Gene and Rawhide see Pop sneaking away with the guns, but just then Mitchell and his men arrive. Before their attack gets started, however, Gene jumps Mitchell and the other men surrender quickly. Gene then races after Pop, who attempts to escape in a motor boat but is shot by Rawhide. Before dying, Pop confesses that he wanted revenge on Cyrus for dissolving their partnership. The Mounties arrive and with order restored, Cyrus, Gene, Rawhide and the Cass County Boys bid Canada farewell.
