One of the major and unanswered questions of World War II and of the attack on Pearl Harbor was that President Franklin Roosevelt knew it was coming and let it happen so we could join England in her fight against Germany.

Only four people knew the real truth about the the attack on Pearl Harbor. The President, General Marshall and Deke Mahan, who became a party to the truth when it was discovered that he understood the Japanese, as well as anyone could understand the japanese.

And, who, then was shocked to learn that the President had someone very high in the Japanese government who could keep them informed of every move the Japanse made; someone who was a shadowy figure, fearful of his life and his family's, if he was ever discovered.

Deke's task was to capitalize on this information source, fighting the F.B.I., J. Edgar Hoover, and an agent, who thought he was a German spy and who went to extraordinary lengths to prove what he thought.

And, also at any cost, to keep the secret from becoming known to the American public, and even from the woman he loved!
