During 1953-1958, as the Cold War intensifies, Korolev is asked to build a rocket capable of carrying a five-ton warhead to America - he designs and constructs the R-7 Semyorka, and is later allowed to use it to launch the first satellite, Sputnik 1. Meanwhile, von Braun struggles to persuade the US government to allow him to launch his own satellite - after Sputnik's launch and the failure of the US Navy to launch a Vanguard satellite, he is finally allowed to launch the first American satellite, Explorer 1.

For the past century, Russian history has also been the history of its security services. They were used by the Soviet state to crush dissent. Millions suffered at their hands. Mass executions, secret wars, spies capable of stealing the atomic bomb, poisoning scandals all add up to the most extraordinary and dangerous security network the world has ever known. But even today, the security network is arguably stronger than ever. This is the History of the KGB, told through its veterans and its victims.
Founded in 1917, Cheka was the predecessor organization of the KGB. Set up as a 'temporary' measure by Lenin, unknown number of Soviet citizens would die at the hands of the secret services as internal dissents in the 1920s. An inglorious chapter is the "Great Terror" phase, when millions of Soviet citizens were convicted and executed in mock trials under Stalin's rule in the 1930s. Outside the Soviet Union, during the WWII they were busy infiltrating German High Command, British Intelligence and America's Manhattan Project. The Cold War had begun in earnest.

By August 1949 the USSR became the world's second superpower, thanks to its spies who had stolen America's atomic secrets. But by March 1953, Stalin is dead and KGB chief, Beria, is executed later the same year. Nikita Kruschev tries to reduce the power of the security service, splitting it into several sections...but it doesn't last and, soon, the KGB is back.
In the USSR, countless KGB operatives spied on opponents of the regime at home, guarded the state and party leadership, and abroad tried to find out as much as possible about the intentions of the NATO countries and, if possible, to sabotage them.

This gripping five-part docuseries marks the 50th anniversary of the fall of Saigon, revealing how a distant war redefined two nations. With unseen footage, candid interviews, and damning presidential recordings, it exposes the political manipulation, battlefield tragedies, and societal fractures that shaped the Vietnam War. From Washington’s strategic missteps to the raw trauma of those on the ground, it shows how the conflict shattered trust in government and left wounds that still resonate today.
The first three episodes trace the war’s slow ignition and its rapid spiral into chaos. They take viewers deep into the secretive early stages of the U.S. military buildup, then shift to the complex realities inside Vietnam, with personal accounts from soldiers on both sides. The series then confronts the shock of the Tet Offensive and the atrocities of Mỹ Lai, dismantling the illusion of a winnable war. These opening chapters set a powerful tone—intimate, harrowing, and unflinchingly honest.
