The billion dollar spy

Sinopse

Leaving the American embassy in Moscow one evening in 1978, the CIA station chief heard a knock on his car window and was handed an envelope containing Soviet military technology research unknown to U.S. intelligence. Over the years, Soviet engineer Adolf Tolkachev handed over tens of thousands of pages of secrets, allowing America to reshape its weapons systems to defeat Soviet radar. Hoffman's compelling account unfolds like an espionage thriller.
