Sergeant Preston of the Yukon

The two survivors of a ship's mutiny, each thinking the other is dead, cross paths at a dance hall in Dawson. Baxter, the ringleader of the mutiny, stabs Donahue, who hadn't participated in the mutiny, in order to eliminate the last witness. Yukon King brings Sgt. Preston to save the stabbed man. The next day Donahue tells his story to Sgt. Preston, who then tracks down Baxter.
