Synopsis by Hans J. Wollstein
The second-to-last American serial ever made, this film series very uneasily combined two popular genres: The Northwest Mounted Police melodrama and Science Fiction. The mix of Medicine Men and airplane dog fights were too ridiculous even for the small fry who, by the '50s, had become the sole audience for this sort of fare. Dennis Moore played an undercover deputy marshal posing as an outlaw in order to infiltrate a gang headed by the nefarious Kenneth MacDonald, a self-styled "Gun Emperor of the Northwest," whose stirring up of the Indians proves a diversion from his smuggling activities. A dark-haired, tight-lipped also-ran cowboy star of the late '40s, Dennis Moore earned the dubious distinction of starring in the two last action serials made in America: Perils of the Wilderness and Blazing the Overland Trail, both low budget affairs heavily padded with stock footage from the genre's glory days in the '30s and '40s.
