Man from Montreal (1939)

Clark Manning (Richard Arlen), a fur trapper, is falsely accused of stealing pelts from other trapper's traps and sets out, with the aid of a Royal Canadian Mounted Policeman, Constanble 'Bones" Blair, to clear his name and find the true thief. He is not helped by Myrna Montgomery (Kay Sutton) who he thinks is his sweetheart and the sister of his friend, Ross Montgomery (Reed Hadley,) but is actually the wife of Montgomery and is part of the frame-up of Manning.
