Sky Bandits

Sgt. Renfrew and Constable Kelly of the Royal Canadian Mounted Police set out to find what's causing a recent run of plane crashes, and their suspicions are heightened after one goes down while carrying a large amount of gold. What the duo discovers, with the help of a science professor's daughter named Madeleine, is a dangerous criminal ring that uses secret radio code and a high-tech weapon designed to bring down flying objects.
