In the heart of the Cold War, they sent him to plot the ultimate assassination. Now they want him dead... It is 1953. Joseph Stalin, the world's most tyrannical dictator, is teetering on the edge of insanity, and about to plunge the world into nuclear chaos. Only one man and one woman can penetrate the Iron Curtain and stop this madman, before it's too late. But someone inside the Kremlin knows. And as the KGB's deadliest manhunter pursues these two CIA-hired assassins, another duel unfolds, between secret warriors of the West and East, with a U.S. agent caught in between. Now that agent must do the unthinkable: find his way to the heart of the Soviet Union and stop the mission he himself set in motion-before it ignites World War III.
