Crashing Thru (1939)

Canadian Mountd Sergeant Renfrew (James Newill) and Corporal Kelly (Warren Hull) are on the way to their Post from Headquarters when the small steamer on which they are traveling is held up. Helpless to stop the thieves from getting away with a gold shipment, they immediately take up the chase when they are freed. They also clear Ann Chambers (Jean Carmen) and her brother, Fred Chambers (Dave O'Brien), of any involvement with the robbery.
