June, 1941. Determined that the United States will be prepared for war, Franklin D.

And no operation is more critical than the one being conducted by hotshot pilot Richard Canidy and his half-German friend Eric Fulmar: to secure the rare ore that will power a top-secret weapon coveted on both sides of the Atlantic—the atomic bomb.
