William Keighley introduces the program and he wonders how we managed to mistake the signs that pointed so clearly to Pearl Harbor, that infamous day of treachery that we observe each 7th December. We know now that Japan's attack was long and carefully planned attack following almost to the letter a secret document known as the Tanaka Plan. This play gives an exciting interpretation of one of the world's great mysteries, the disposition of that document in producer William Cagney's screen hit Blood on the Sun. 

James Cagney and Sylvia Sidney star in their original screen roles.
