A chronicle of the making of Disneynature’s Dolphin Reef, the story of a young Pacific bottlenose dolphin named Echo. From wave surfing with dolphins in South Africa to dancing with humpback whales in Hawaii, filmmakers go to great lengths - and depths - to shed new light on the ocean’s mysteries.

Echo is a youngster who can't quite decide if it's time to grow up and take on new responsibilities-or give in to her silly side and just have fun. Dolphin society is tricky, and the coral reef that Echo and his family call home depends on all of its inhabitants to keep it healthy. But Echo has a tough time resisting the many adventures the ocean has to offer.

David Attenborough takes viewers on a breathtaking journey showing there is nowhere more vital for our survival, more full of life, wonder, or surprise, than the  ocean. Through spectacular sequences featuring coral reefs, kelp forests and the open ocean, Attenborough shares why a healthy ocean keeps the entire planet stable and flourishing.
