The last wilderness on Earth is beneath the waves.

Far below the surface of the Pacific lies a world almost completely hidden from human eyes. How Deep Is Your Love follows a team of marine biologists as they descend thousands of metres into the deep ocean, searching for and documenting species that science has barely begun to understand. Their discoveries reveal an extraordinary ecosystem thriving in darkness — but also expose a looming threat in the form of deep-sea mining. Eleanor Mortimer's immersive documentary balances scientific adventure with an urgent environmental question: what happens when the desire to exploit the ocean's resources collides with the need to protect one of Earth's last unexplored frontiers?
