1956. A celebrated Russian author is writing a book, Doctor Zhivago, which could spark dissent in the Soviet Union. The Soviets, afraid of its subversive power, ban it. But in the rest of the world it's fast becoming a sensation. The CIA plans to use the book to tip the Cold War in its favour. Their agents are not the usual spies, however. Two typists - the charming, experienced Sally and the talented novice Irina - are charged with the mission to smuggle Doctor Zhivago back into Russia by any means necessary. It will not be easy. There are people willing to die for this book. But they cannot fail - as this book has the power to change history.
