An ancient piece of corroded metal is more than it seems: an alien-looking device of intricate dials and cogs; there are over 30 gears inside and some gears have up to 65 teeth on them. Using cutting-edge imaging technology, experts examine what could actually be a 2,000-year-old computer. How can an ancient Roman cup change colour? It's not an optical illusion. It really does change colour from red to green.
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.
In episodes 15 and 16, the war begins to close in on the Axis powers not only across battlefields, but inside the societies that created it. Germany and Japan face the turning tide in radically different ways: Hitler’s regime tries to preserve the illusion of normal life while driving production through propaganda, forced labor and terror, while Japan demands sacrifice, austerity and total obedience from its people as American submarines cut the lifelines of empire. As bombing raids, shortages and fear shatter the home front, the documentary reveals how nations built on conquest begin to feel the terrible cost of the war they unleashed. The story then moves into one of the most powerful chapters of resistance in occupied Europe. As Allied armies advance from Normandy and Soviet forces push from the east, ordinary people and underground fighters rise against Nazi rule in France, Poland and even inside the machinery of extermination itself. From coded BBC messages and the liberation of Paris to the doomed Warsaw Uprising and the desperate courage of prisoners documenting the horrors of Auschwitz, these episodes show war at its most human and devastating: A struggle not only between armies, but between tyranny and the refusal to be erased.
