Weapons capable of wiping out humanity

An ordinary businessman is caught up in a middle of Cold War and the brink of thermonuclear warfare. In the dangerous world of spies where things can go sideways in a blink of an eye, he's perhaps not the right man for the job, but he still could save the world from total annihilation as the Soviets and the Yankees are threatening to shoot rockets back and forth like there was no tomorrow! A stylish and in the end pretty grim espionage thriller based on a true story.
