Far out on the open sea, an expedition vessel travels toward one of the most remote regions on Earth, the Clarion–Clipperton Zone, twelve days from the nearest land.
Here, darkness, silence, and immense depths conceal an unexplored universe.
How Deep Is Your Love follows a group of marine biologists trying to understand life in this unknown world, while grappling with the question of whether their presence risks harming what they seek to protect. A visually hypnotic and deeply absorbing journey in which every discovery reshapes our understanding of the planet.
Eleanor Mortimer has created a nature documentary like no other. How Deep Is Your Love weaves awe-inspiring footage of this breathtaking realm with a looming sense of urgency as mankind’s progress threatens to upend these delicate eco-systems.
