Beneath the surface of the ocean exists an incredibly hostile world - an icy world immersed in eternal darkness where the pressure is phenomenal. This world is the abyssal domain - the largest habitat on our planet.
Yet, some air-breathing, young-feeding marine mammals, like us, spend much of their time in this dark world. Scientists are now discovering that the depths reached by these ocean giants are much greater than previously thought.

Using transmitter beacons worn by the animals, abyssal cameras and 3D scan images, this film accompanies and illustrates a contemporary scientific revolution. Constructed according to a dramatic progression towards the abyss - from the shallowest to the deepest dive - it brings to the forefront the often unknown animals and their remarkable physiological adaptations to the pressures of the great depths.
