The film is a cinematic quest to find the '52 Hertz Whale,' which scientists believe has spent its entire life in solitude, calling out at a frequency that is different from any other whale. As we search for this elusive creature, we will explore the phenomenon of human reaction to its plight, while revealing its connection to the growing epidemic of loneliness in our interconnected world.

In Southeast Alaska, there's an ice-bound Eden that harbors possibly the richest temperate rainforests of all. Where the coastal mountains meet the Pacific, lays the Alexander Archipelago, a remote island chain running for almost 300 miles along the Alaskan Panhandle. This frozen frontier is one of the last great wildernesses of North America. And a stronghold for the country's highest diversity of megafauna, feasting on the abundance of fleeting summers to make it through relentless winters.

Fathom is a visual and aural wonder of a documentary that follows researchers working to finally decode the communication of humpback whales. Dr. Ellen Garland and Dr. Michelle Fournet embark on parallel journeys on opposite sides of the world, as they seek to better understand whale culture and communication. The film uniquely reveals a deep commitment and reverence to the scientific process and the universal human need to seek answers about the world around us.
From hypothesis to groundbreaking experiences in the field, 'Fathom' showcases the passion, curiosity, collaboration, perseverance and work it takes for leading scientists to make scientific discoveries.

Whales have long been a profound mystery to us. They live in a world so removed from our own that we can barely imagine their lives. Their environment is different, their senses are different, their relationships are different. How might such almost alien creatures see the world?, Narrated by David Attenborough.

Far from land, where few of us ever venture, is the ocean beyond the boundary of any country. Largely ungoverned, wild, and lawless. Venture into the deep, dark and desolate oceans that are home to an abundance of beautiful - and downright strange - creatures.

Immense shoals of fish throng our shallow seas. Small fish, in turn, sustain bigger ones. The rich coastal seas are the fishing grounds of our planet and can provide an abundance of food for wildlife and humanity. The seas fringing land make up less than a tenth of the world's oceans but 90 percent of marine creatures live in coastal waters, from fearsome sharks to lowly urchins. Protecting these habitats is a battle humanity must win.
