Washington D.C., 1953. The Cold War is heating up while the CIA is reeling from a double agent in their midst. Someone is selling secrets to the Soviets, compromising missions around the globe. Undercover agents have been assassinated and anti-Communist plots are being cut short. The CIA director knows any news of the traitor would be a national embarrassment and compromise the entire agency. George Mueller seems to be the perfect man to help find the mole, but soon suspicion begins to fall on him as well. Until the traitor is found, no one can be trusted.
