PLANET EARTH's premiere episode, "Pole to Pole," ties the series together with a fresh understanding of how life in every nook and cranny of the globe is connected -- from the highest mountains and darkest caves; shallowest water and deepest oceans; ice-covered lands and great plains; untamed jungles and giant forests; to freshwater and the harshest deserts. The sunward tilt of Earth's orbit dictates all our lives, creating the seasons that trigger one of the greatest spectacles in the world -- the mass migration of animals. It's a unique view of the majesty of our planet and the amazing creatures that live here.
