When enemy agents try to snatch the secret files of Count Dietrich von Kronstein––who has helped refugees escape from behind the Iron Curtain to the West––the count seeks TEEN's help. The U.S. intelligence agency dispatches its two most skilled agents, Chris Cool and his Apache pal Geronimo Johnson, to the count's castle in Bavaria. They arrive in time to witness his funeral! During the services a blowgun dart narrowly misses Chris, but kills a diplomat from the Arab country of Marak.

       What happens next catapults Chris and Geronimo into a terrifying race to Marak to East Berlin and back to Bavaria, to prevent an international bargain which could destroy the free world.

       The TEEN agents match wits not only with the deadly espionage organization TOAD, but also with the elusive and feared Red spy known as the Ace of Shadows.
