December, 1944: The Nazi supervillains in the SS Occult Bureau have learned that Glen Miller's horn is actually an ancient Instrument of Power... and Hitler wants it. Now, as Captain Miller flies to a USO concert in France in the same plane as stage magicians Tazara and Magerock, piloted by Commander Harry Bailey, a nefarious spell is cast to take mystical remote control of that plane and divert it to Berlin. But the ghost of Amelia Earhart has overheard this evil plot and carried a warning to the Allies, specifically to a former German pilot from WWI now incarnate as a shambling heap of swampy muck... and this Heap manages to get word of the scheme to four Allied heroes. Now, adventuring archaelogist Montana Johnson, winged wonders Falconman and Falcongirl, and the jetpack wearing test pilot known as the Rocket Ranger all race to intercept Miller's sorcerously hijacked aircraft in an experimental rocket plane prototype designed, built, and piloted by globetrotting crimebuster and scientific prodigy Doc Raven. Yet Nazi wizards Myron Moulton, Vassily Van Dammerung, Diabolico, Dr. M, and Reichsfuhrer Heinrich Himmler have spun a web of treachery and terror in their quest for the Horn of Power, and they will allow nothing to stand in the way of them acquiring it. Will a handful of desperately racing heroes be able to forestall the entire mystic might of the Third Reich?
