Washington D.C., 1953. The Cold War is heating up: McCarthyism, with all its fear and demagoguery, is raging in the nation's capital, and Joseph Stalin's death has left a dangerous power vacuum in the Soviet Union. The CIA, meanwhile, is reeling from a double agent within 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 in ruthlessly efficient fashion. The CIA director knows any news of the traitor, whose code name is Protocol, would be a national embarrassment and compromise the entire agency.
