BBC - Nuclear Secrets Set One (2007) Part 2 Superspy

At present the total nuclear arsenal of the world is no less than 27,000 nuclear warheads. Nine countries in the world (probably) have nuclear weapons and a dozen more have access to the resources and technology needed to produce such a weapon. Nuclear Secrets is a series of spy thrillers exploring the key turning-points in the race for nuclear supremacy. Despite being an ally during World War II, the Soviet Union launched an all-out espionage effort to uncover the military and defense secrets of the United States and Britain in the 1940s. As the top-secret plan to build the bomb, called the Manhattan Project, took shape in the United States, the Soviet spy ring got wind of it before the FBI knew of the secret program's existence. The Atomic Spy Ring was established by the Soviet Union during World War II and included some of the best known names in the world of espionage. Barely four years after the United States dropped two atomic bombs on Japan in August 1945, the Soviet Union detonated its own at the Semipalatinsk Test Site in Kazakhstan in August 1949, much sooner that expected. The race to build the hydrogen bomb took the world to the edge of apocalypse. It set off a real-life action thriller to control the most powerful force on the planet. This prestigious BBC series using dramatized reconstructions and CIA and KGB archives reveals the true story of the race for nuclear power, from the creation of the A-bomb to the present day market in military secrets across the world.

Part 2 Superspy

One man's mission started the Cold War. Superspy unearths how Klaus Fuchs stole the secrets of the Hiroshima bomb and gave these confidential details to the Soviet Union. During the Second World War, German refugee Klaus was posted to the highest security weapons laboratory in America. His assignment was to help design the world's first weapon of mass destruction. After joining Robert Oppenheimer's team, he became an expert on plutonium and secretly plotted how to contact the Soviet spymasters. Under the eyes of the FBI, he slowly pieced together America's atomic secrets and copied out his notes. Evading security, he smuggled out the complete blueprint of the Nagasaki A-bomb. In January 1942, Klaus met up with a young mother – who was, in fact, a Soviet spy – and disclosed the classified information of how to construct an A-bomb. In the spring of 1945, he conducted a series of meetings with his Soviet courier, “Harry Gold”. By 1949, the FBI were on the hunt for the traitor. Klaus escaped to England, where he started a job which placed him at the heart of the British nuclear establishment. While in the UK, he continued to sell secrets. The superspy's downfall came when he confessed all to MI5, whom he told “It's as though my mind has two compartments.” But the consequences of his actions led the world to fear nuclear Armageddon.
