In episodes 3 and 4, a seemingly simple ingredient becomes the invisible force that has shaped civilizations, fueled exploration, and quietly dictated the fate of empires. From ancient trade routes to modern industry, salt emerges not just as a seasoning, but as a powerful driver of human history and survival. At the same time, the story shifts to something far more familiar yet equally unsettling: the global dominance of a single type of banana. What appears to be abundance hides a fragile system built on uniformity, where one disease could wipe out a staple food relied upon by millions. As the journey unfolds, the narrative exposes the hidden cost of convenience and monoculture, revealing how the loss of biodiversity is not a distant ecological concern but an immediate threat to our food security and future. With striking connections between past and present, these episodes invite you to rethink what you eat, where it comes from, and how something as ordinary as salt or a banana could hold the key to understanding the balance—and imbalance—of our world.
In episodes 5 and 6, Ragnar’s rise becomes a mortal threat to Earl Haraldson, as prophecy, fear and ambition turn Kattegat into the center of a brutal struggle for power. After the Seer warns that Ragnar seeks his death, Haraldson moves from suspicion to violence, attacking Ragnar’s home and torturing Rollo in an attempt to destroy the challenger before he can grow stronger. Wounded, hunted and betrayed, Ragnar must decide whether survival is enough, or whether the time has come to confront the man who has ruled his people through fear. The conflict explodes into a direct challenge that will decide the future of Kattegat. Still weakened but driven by destiny, Ragnar faces the Earl in a duel where honor, vengeance and leadership are at stake. What follows is not only a fight between two men, but the collapse of an old order and the birth of a new one. With funerals, rituals, loyalty and sacrifice surrounding the change of power, these episodes reveal the dark beauty of Viking tradition and the moment when Ragnar Lothbrok’s legend truly begins to rise.
In episodes 5 and 6, you can see how two everyday foods open the door to something far bigger: Memory, survival, tradition and the uneasy bond between humans and the natural world. One journey takes you to La Alberca, in Spain, where the pig is not just an animal but part of a living ritual charged with history, pride and contradiction. The other leads into the rice fields of Kerala, India, where every grain carries the weight of climate, heritage and the fight to preserve ways of life that are slipping away. These chapters do far more than show food on a plate: they reveal beauty, tension and the hidden forces that sustain entire cultures, making each scene feel rich, intimate and impossible to forget.
In episodes 3 and 4, the journey intensifies as Will Smith pushes deeper into both the physical and emotional extremes of the planet. In the Amazon, he ventures into dense, unforgiving jungle in search of the elusive green anaconda, confronting fear, danger, and the raw power of one of Earth’s most mysterious predators. Guided by local experts, the expedition becomes a test of courage and trust in a world where nature sets all the rules. The adventure then shifts dramatically to the Himalayas, where the challenge is no longer survival but meaning. High above the clouds, Will explores the idea of happiness alongside monks, scientists, and mountain communities, discovering how isolation, altitude, and ancient wisdom reshape the human mind. Together, these episodes connect the wildness of nature with the inner journey of self-discovery, revealing that the greatest expedition may be the one within.
In the final three episodes of the series, Chris Packham follows three extraordinary evolutionary journeys to discover how the relentless demands of survival transformed simple early animals into some of the most remarkable creatures alive today. In Borneo, the voracious appetite of the bat leads back more than half a billion years to the origins of the through-gut, the first anus, heads and jaws, revealing how the need to find and consume food helped reshape animal life and ultimately produced the bat’s extraordinary powers of hearing. In the Bahamas, the intelligence of dolphins opens an even deeper story: from ancient cells able to sense light to the evolution of eyes, complex brains, sophisticated senses and the remarkable minds of modern dolphins. The journey culminates with one of nature’s supreme athletes. Tracing the horse’s ancestry through hundreds of millions of years, Packham reveals how primitive muscle cells evolved into increasingly powerful systems for movement, how beating hearts supplied those muscles with oxygen, and how limbs became ever more effective tools for locomotion. Slithering, swimming, walking and running eventually converge in an animal built for extraordinary speed and endurance. Together, these final episodes reveal a breathtaking truth: hunger, perception and movement were not merely necessities of survival—they were powerful evolutionary forces that helped create the astonishing complexity of animal life.
Guided by Stanley Tucci, this documentary journeys into the heart of Italy to reveal the country as it truly is, complex, contradictory, and deeply rooted in its culinary traditions. Through food, Tucci uncovers stories of history, identity, and innovation, showing how every dish reflects centuries of culture, migration, and local pride. What emerges is not a postcard Italy, but a living, evolving nation where cuisine is a language spoken by everyone. In the first three episodes, Tucci immerses himself in Tuscany, savoring the artistry of its cuisine while exploring Florence and Siena, where Renaissance creativity still shapes the table. He then heads north to Italy’s industrial regions, discovering cutting-edge gastronomy and futuristic farming, from high-tech agricultural labs to unexpected gourmet food found at service stations. Finally, in the German-speaking Alpine north, he explores a dual cultural identity through mountain dishes, skiing traditions, and glacial river fishing, revealing how history, borders, and landscape have forged a cuisine unlike any other in Italy.
As the journey unfolds, the narrative exposes the hidden cost of convenience and monoculture, revealing how the loss of biodiversity is not a distant ecological concern but an immediate threat to our food security and future. With striking connections between past and present, these episodes invite you to rethink what you eat, where it comes from, and how something as ordinary as salt or a banana could hold the key to understanding the balance—and imbalance—of our world.
