From the first shots fired in Poland to the dawn of the atomic age, this gripping documentary revisits the most devastating conflict in modern history with the scale, urgency, and human focus it demands. Through decisive battles, world-changing leaders such as Winston Churchill, Franklin D. Roosevelt and Josef Stalin rare wartime perspectives, and the immense suffering of soldiers and civilians, it shows how total war reshaped nations, destroyed millions of lives, and forced humanity into a new and terrifying era. The first three episodes plunge directly into the war’s explosive beginnings. In September 1939, Germany invades Poland after a secret pact between Adolf Hitler and Josef Stalin clears the path for aggression, setting Europe on fire once again. As Nazi forces crush the Netherlands and Belgium and drive west, Churchill prepares Britain for an air assault while Roosevelt races to turn American industry into a weapon of survival. The story then moves to Operation Barbarossa, Hitler’s colossal surprise invasion of the Soviet Union in 1941, the largest and most costly land offensive ever launched, where ambition, brutality, and resistance collide on an unimaginable scale.
In episodes 11 and 12, the Allies try to turn victory in North Africa into a direct road toward Nazi Germany, only to discover that Italy will be anything but the “soft underbelly” Winston Churchill imagined. From Sicily to Salerno, Anzio, Monte Cassino and the long road to Rome, the campaign becomes a grinding test of endurance, strategy and sacrifice. What was hoped to be a swift breakthrough into the heart of Hitler’s Reich turns into months of mud, mountains, shattered towns and devastating losses, revealing the brutal cost of forcing open a new front in Europe. The story then rises into the skies, where another deadly battle is being fought above the continent. Allied bomber crews fly from England into the heart of Nazi-occupied Europe, facing freezing altitude, flak, fear and the lethal power of the German Luftwaffe. As B-17s, fighter escorts and air commanders struggle to win control of the air, every mission becomes a gamble between destruction and survival. Together, these episodes show a war closing in on Germany from the ground and from the sky, where courage, technology and human endurance collide on a terrifying scale.
In episodes 3 and 4, Ragnar returns from England with treasure, prisoners and the first proof that his forbidden dream was not madness, but the beginning of a new world of opportunity. Yet victory quickly turns dangerous when Earl Haraldson seizes the riches for himself and forces each man to choose only one reward. Ragnar’s choice is not gold, but Brother Athelstan, a captured monk whose knowledge of England may prove more valuable than any silver. As celebration gives way to suspicion, the raid becomes a threat to the old order, and Ragnar’s growing fame starts to look like a direct challenge to the Earl’s power. With permission now granted to sail west again, Ragnar and his crew return to England in search of greater wealth, deeper secrets and more dangerous enemies. But every success abroad increases the danger waiting at home. In Kattegat, Haraldson turns against Ragnar, accusing him of murder and dragging him before the law in a trial that becomes a battle for loyalty, honor and survival. Between Saxon lands, Viking ambition and the politics of a ruthless chieftain, these episodes turn exploration into open conflict and show how Ragnar’s legend begins to threaten everyone who stands above him.
In episodes 17 and 18, the Second World War enters its most devastating final phase as two distant battlefields become the stage for unimaginable destruction. Across the Pacific, American forces fight island by island against an enemy determined to resist to the very last soldier. Every beachhead is won at an unbearable cost, revealing a campaign where courage, sacrifice and survival are pushed beyond all human limits. As casualties mount and Japan refuses to surrender, the conflict descends into one of the bloodiest chapters in military history. Meanwhile, the Soviet Union launches its overwhelming final offensive into the heart of Nazi Germany. As the Red Army closes in on Berlin from the east and Western Allied forces advance from the west, Hitler's collapsing regime makes one last desperate stand. Street by street, the battle for the German capital becomes a brutal struggle that seals the fate of the Third Reich. Through extraordinary archival footage and firsthand accounts, these episodes reveal how two immense campaigns—one in Europe and one in the Pacific—brought the deadliest war in history to its dramatic and unforgettable conclusion.
In the first three episodes of Season 2, Ragnar Lothbrok is thrust into a brutal conflict that threatens both his family and his ambitions. Fighting alongside King Horik against Jarl Borg, he is forced to confront the ultimate betrayal when his own brother Rollo stands on the opposite side of the battlefield. But victory brings little peace. Princess Aslaug arrives in Kattegat carrying Ragnar’s child, shattering his marriage to Lagertha and dividing his family just as Ragnar’s dreams of returning west begin to grow. Ragnar is Earl and prepares a new expedition to England. A violent storm scatters the Viking fleet and drives the survivors onto the shores of Wessex, where they encounter a formidable new ruler, King Ecbert. Raids, ambushes and bloody clashes mark the beginning of a dangerous struggle for power, while Athelstan’s knowledge of England becomes increasingly valuable. Yet the greatest threat may be waiting at home: as Ragnar pushes deeper into Wessex, the embittered Jarl Borg turns his attention towards Kattegat. These opening episodes launch the season with brother against brother, Viking against Saxon, and ambition, loyalty and revenge threatening to tear Ragnar’s world apart.
As climate chaos intensifies, animals across the planet are being pushed into conditions their bodies and instincts were never designed to face. Floods arrive where drought once ruled, storms grow stronger, seas warm and familiar habitats disappear. Narrated by Andrew Lincoln, this six-part natural history series follows wildlife confronting these extremes at close range, revealing not only the destructive power of a changing climate but also the extraordinary ingenuity, resilience and adaptability animals use to survive. In the first three episodes, the struggle begins on an increasingly extreme Earth. Burrowing owls on the North American Great Plains race to protect their chicks from tornadoes, cheetahs in Kenya battle record floods, polar bears search for vanishing sea ice and chimpanzees survive severe drought by digging their own filtered water holes. Rising waters then transform entire ecosystems: pygmy elephants face monsoon floods in Borneo, a platypus is swept into a violent flash flood in Australia, and a lone lioness in the Kalahari turns an unexpected flood into a rare hunting opportunity. Finally, along the world’s coasts, Caribbean flamingos confront a category-five hurricane, anole lizards cling on through violent winds, California sea otters struggle through huge storms and collapsing kelp forests, while clownfish on the Great Barrier Reef face a marine heatwave that threatens the very anemones on which their families depend.
