Will Smith (Welcome to Earth, One Strange Rock) leads viewers on an astounding journey from the bottom of the planet to its top — covering 26,000 miles from the South Pole to the North Pole — to unlock the mystery of Earth’s astonishing diversity and alchemy. Filming for more than 100 days, the series documents his journey across all of Earth’s biomes: polar ice, desert, jungle, mountain, savannah and swamp. In each location, the explorer Smith and his film crew will embed with local communities and experience firsthand what it is like to live in some of the most amazing and extreme landscapes on the planet.
