Meryl Streep narrates the sweeping visual that emphasizes the value of our world's oceans, and how they and the life thriving within depends on us to maintain their majesty. Through research (via whale watchers and oceanic research teams), casual observance through surfers, reverence (during Coast Guard rescues) and daily life (spear fishermen in the Palau islands), we are shown how the oceans are interconnected, and that life can be found in even the darkest corners of the sea.
