In the 56th (and next-to-last serial) made by Columbia Pictures, Montana Deputy Dan Lawson, posing as an outlaw called Laramie, goes to the Canadian northwest on the trail of Bart Randall who is wanted for murder and bank robbery in the states. In Canada, Randall is a little more upscale and uses a hydra-plane and a fake totem to over-awe the Indians. Laramie is aided in his search by RCMP Sergeant Gray and by Donna Blane, who is suspected at first of giving information to Randall, but who is actually a Canadian secret agent investigating Randall's gun-trading with the Indians.
