Benjamin Ripley, young spy-in-training at the Central Intelligence Agency, has always been impressed by super-cool, incredibly capable spies from movies. But there have been plenty of real spies throughout history that no one has heard of because they operated in secrecy on classified missions. But now, some of those amazing stories are declassified…

Join Ben as he shares the true stories behind World War II’s courageous spies, their inventive commanders, and the incredible things they did, like commando raids, code-breaking, double-crosses, disinformation, and inventing shark repellant and exploding pancake batter (really). There are amazing stories about famous spies like Julia Child, John Ford, and Sterling Hayden, plus countless others who risked their lives and took great risks to keep the world safe from evil.
