In the final two episodes, the experiment moves from theory to real life as the twins are forced to take full control of their food choices after moving out on their own. Cooking becomes a daily challenge, exposing how habits, convenience, and culture shape what we eat. At the same time, innovators pushing plant-based alternatives step into the spotlight, as growing concerns around animal products raise urgent questions about health and sustainability. As the study reaches its conclusion, the results are finally revealed. Detailed analyses of weight, gut health, and brain function confront the twins with clear, and sometimes surprising, consequences of their diets. What began as a personal test widens into a broader reflection on the future of food, as momentum builds around a changing food industry and the choices that may redefine how we eat.
This eye-opening documentary puts a simple but provocative question to the test: how much does what we eat really shape our bodies and our health? In a tightly controlled scientific experiment, identical twins adopt radically different diets and lifestyles for eight weeks, allowing researchers to isolate the impact of food itself. By combining cutting-edge science with deeply personal experiences, the series reveals how diet influences everything from energy and metabolism to long-term wellbeing. In the first two episodes, the experiment begins as each pair of twins commits to either a plant-based or an omnivorous diet. As they adjust to unfamiliar routines, some changes feel surprisingly easy while others expose cravings, doubts, and unexpected challenges. Along the way, questionable dietary advice is put under the microscope, and a celebrity chef rethinks his approach to cooking, highlighting how habits, culture, and taste all collide when science meets the dinner table.
This high-stakes documentary follows climber Alex Honnold as he attempts the unthinkable: scaling Taipei 101, one of the tallest skyscrapers on Earth, without ropes or safety gear—and doing it live. With cameras rolling in real time, every movement becomes a moment of tension, turning a feat of athletic precision into a global spectacle where a single mistake could be fatal. As the climb unfolds, the film pulls viewers inside Honnold’s mindset, revealing the discipline, focus, and psychological control required to face extreme exposure hundreds of meters above the city. Blending vertigo-inducing visuals with the immediacy of live broadcast, it becomes a gripping meditation on risk, human limits, and what drives someone to push beyond fear in front of the world.
In the final three episodes, the journey deepens into a powerful exploration of culture, survival, and science at the planet’s edges. On a remote Pacific island threatened by rising seas, Will Smith joins Dr. Walworth and John Aini to document a dying language spoken by only five people, turning marine research into an intimate race against time to preserve human memory. The mission reveals how climate change erodes not just coastlines, but identities. The adventure then shifts to extremes of land and ice. In the Kalahari Desert, Will learns survival from the San people, confronting the limits of his endurance during a traditional hunt with guide Kane Motswana. The odyssey culminates beneath the ice of the North Pole, where, alongside polar ecologist Allison Fong, a daring dive to collect critical samples is jeopardized by a sudden storm and equipment failure. What follows is a gripping test of courage and teamwork that redefines heroism at the end of a 100-day quest.
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.
Inspired by his late mentor, Will Smith embarks on a 100-day, pole-to-pole odyssey that pushes him far beyond his comfort zone. Traveling alongside scientists, explorers, and local experts, he climbs remote mountains, dives beneath polar ice, and confronts the raw power of nature. The journey blends adrenaline and curiosity, revealing how extreme environments shape life—and how facing the planet’s edges can reshape us, too. In the first two episodes, the adventure begins with sweeping ambition and immediate immersion. Smith sets out on the global route with National Geographic, then plunges into the Amazon rainforest, tracking dangerous wildlife and learning from those who know the jungle best. It’s a vivid opening that sets the tone for a quest defined by discovery, risk, and awe at the natural world.
As the study reaches its conclusion, the results are finally revealed. Detailed analyses of weight, gut health, and brain function confront the twins with clear, and sometimes surprising, consequences of their diets. What began as a personal test widens into a broader reflection on the future of food, as momentum builds around a changing food industry and the choices that may redefine how we eat.
