Trail of the Yukon

Matt Blaine and his son, Jim, and their men, rob John Dawson's bank, although Jim doesn't approve, even though Dawson jumped Matt's mining claim. Their accomplices double-cross them and the Blaines escape by canoe. They are followed and meet Royal Candian Mounted Policeman Bob McDonald, who helps them fight until all three men are wounded. Aided by Chinook, McDonald's dog, they escape but Matt dies. McDonald then sets out to prove that Dawson was the real culprit.
