Ava is lonely. Like many Greenland sharks, she has lived a long time. So long that she can't remember where she came from or what happened to her family. The fish and whales don't want to help her. But an albatross named Chris is willing to come with her in search of answers. Join them on an adventure to the deepest parts of the sea and Ava's past, to a time when the creatures of the deep knew her kind.
