After a spate of hijacks and thefts of lorries carrying strategic items, Government agents Hal (Walter Reed) and Sam (John Pickard) are bought in to foil the crooks. The crimes are being organised by a shadowy figure who only speaks behind a glass. We do see who it is, one of the logistic company bosses, in the final showdown after many cliff hangers...
This is a reasonable if not overly spectacular serial. It is rather restrained compared to some examples of the genre but is pretty well made throughout with some good cliff hangers, the best being the first one with the exploding rail car in a tunnel.
Some of the secondary characters including Kay (Mary Ellen Kay) don't really get as much screen time as they probably deserve.
