Producer Julian Lennon collaborates with screenwriter/director Kim Kindersley to offer viewers a rare glimpse into a tribal culture that has endured for centuries and whose detailed creation story revolves around the most majestic mammals to swim the seven seas. Extensive underwater footage serves as the spectacular visual backdrop to ancient legends that gradually unfold to offer a fascinating glimpse into humankind's past, and a potentially dire look into our future. By exploring the connection between the so-called "mothers of the sea" and the ancient civilizations whose very culture was based on their existence, the filmmakers call upon viewers to create peace and unity on Earth by embracing every living being and recognizing that all life forms, no matter how different they may appear, are all intricately linked together.
