In time-honored fashion, a couple of supporting players -- George Dolenz and Bill Kennedy -- found themselves elevated to starring roles in this minor Universal serial. They played Royal Canadian Mounted Police officers investigating the murder of a miner. The story, of course, was less important than speed and action, which directors Ray Taylor and Lewis D. Collins delivered in typical slap-dash Universal style. Starlet Daun Kennedy did not make much of an impression as the imperiled leading lady, and former star Robert Armstrong (of King Kong fame) was wasted in a subordinate role. Rondo Hatton, a non-actor whose grotesque appearance (caused by acromegaly, the so-called "Elephant Man" disease) was tastelessly exploited by Universal in the '40s, appeared as one of the outlaws.
