This is the story of two marine giants… the largest predator on Earth, and one of the largest of all squid. One predator. The other prey. And following them, a team of marine biologists who want to attach a remote camera to a sperm whale to record what happens a thousand feet beneath the sea. This high seas adventure will test everything they've got. It's a mission into the deep, a mission into the unknown…. A scientific quest to understand one of the great wildlife mysteries on our planet.
