The Great Barrier Reef (2017)

Plot

Marina Kazankova, a celebrated actress and world champion freediver, guides us through the breathtaking wonders of Australia's Great Barrier Reef. This UNESCO World Heritage Site faces grave threats from global warming and ocean acidification, making its preservation more urgent than ever. From Hardy Reef and the Whitsunday Islands to the pristine Coral Cays, she introduces us to an incredible cast of marine life, including whale sharks, sea turtles, and the rare giant grouper stretching up to three meters long. Together, we explore hidden caves, eerie shipwrecks, and the reef's astonishing horizontal waterfalls—all beneath the surface of the world's largest living structure.
