Hidden Enemy

Reporter Warren Hull's father, George Celeveland, has invented a new metal that's lighter than aluminum and stronger than steel. The War Department is interested. Unfortunately for him, he hands it over to industrialist John Sheehan in return for a line of guff. At the same time, a ring of spies headed by Wilhelm von Brincken already knows about it and are willing to do what they must to get their hands on it. There also seem to be two other spy organizations with guns after it. And what to make of Kay Linaker, who claims to be a newspaperwoman, but no one at his paper has heard of her?

It's spies with guns who get into fistfights in which everyone's hat seems glued to the fighters' heads, as two-fisted Hull gets fired and tries to find out the story as a way back to a paycheck. Director Howard Breatherton directs competently, but the whole thing looks like it was intended as a serial instead of a one-hour second feature.
