David Attenborough celebrates the amazing variety of the natural world in this epic documentary series, filmed over four years across 64 different countries.

Set nearly a decade after the finale of the original series, this revival follows Lorelai, Rory and Emily Gilmore through four seasons of change.

David Attenborough travels to the end of the earth, taking viewers on an extraordinary journey across the polar regions of our planet.

Once upon a time, there was Winter.

Winter was once the only season in the world-but such an existence was too lonely to bear, and so it created Spring to love. Before long, the earth wished for more time to rest in the cycle, and Summer and Autumn were born. The ones who carry the cycle are called the Agents of the Four Seasons. Hinagiku, the Agent of Spring, disappeared from this land ten years ago, taking the season of spring with her. Now, after incredible hardship, she has returned to restore the cycle to its proper state-and, as in the myth passed down since the dawn of time, she sends her love to Winter.

Filmed in over 60 different locations this epic documentary series will draw on the most spellbinding and dramatic stories from all corners of the globe. It will reveal the ways all life is connected and how natural events affect animals.

Narrated by actor Laura Carmichael, this six-part documentary series charts the planet’s most spectacular events of migration, rebirth and transformation. Over the course of a turbulent year, we witness how finely tuned creatures face the Earth’s seasonal patterns. However, in the 21st Century, these patterns are becoming more extreme, less predictable and dangerously unreliable. Across the globe, we witness the drama and the spectacle. No matter what time of year it is, somewhere on Earth something miraculous is happening.
