The Falcon and the Snowman

Christopher Boyce, an expert in the sport of falconry and the son of a former FBI special agent, gets a job at a civilian defense contractor working in the so-called "Black Vault," a secure communication facility through which flows information on some of the most classified U.S. operations in the world. Boyce becomes disillusioned with the U.S. government through his new position, especially after reading a misrouted communiqué dealing with the CIA's plan to depose the Prime Minister of Australia. Frustrated by this duplicity, Boyce decides to repay his government by passing classified secrets to the Soviets.
