Join us on a one-of-a-kind journey to a place that’s more extreme, more hostile — and unexplored — than outer space. A place with more resources to gain, and more undiscovered life to protect, than anywhere in our universe. A place where only one vehicle can take you. A place so dangerous, that only two drivers know how… Until now. Australian journalist Rachael Thornton gains unprecedented access to the first major Chinese expedition to the deep sea. China owns the world’s deepest diving 3-person research sub, and on this voyage, one woman makes history as a deep sea sub pilot, while another seeks answers to the origins of life on Earth. Rachael’s warmth and determination bring to life the drama, dangers and victories of blazing new trails when the stakes are extremely high. No sub has ever taken 3 humans to full ocean depth. What will crack? Who might die? For precious resources and mysterious new life, the deep-sea remains our greatest challenge.
