On a hidden ranch in the hills of Mexico, a Nazi spy prepares a plan to disrupt relations between Mexico and America. A government official is to be tied up, and thrown from a plane. The dire incident has the attention of David Harding, and he learns about new technologies with special light bulbs. It’s thought the high frequency lights are directing enemy planes. If they can be detected, a raid can be made on the enemy hideout. Sure enough, houses are identified that lead to the ranch used as a base.
David has a secret about that official who was killed. How will it help him on his raid? Posing as a German operative, David infiltrates the operation. A scream in the dark signals that all may not be going well.
The trap begins closing when support planes are spotted in the skies. Meanwhile, David Harding arrests the spies, and a counter operation is put into place to glean intelligence on the Nazi’s who may arrive in the future. Will it work? Of course it will, for the first time since the Crusades, a great Christian army has arisen to drive out all the Nazi forces. Or so says David Harding.
