Narrated by Sir David Attenborough, Blue Planet III marks the return of the franchise that transformed audiences' understanding of life beneath the waves. Twenty-five years after the groundbreaking original series first brought the oceans into homes around the world, the new series reveals extraordinary new stories from some of Earth's most important and least understood environments.
