Riding the Ocean Dragon (2017)

Australian Rachael Thornton goes where no Western documentary filmmaker has ever been. She is the only non-Chinese member of the first major scientific mission of Ocean Dragon, China's powerful manned submersible. Rachael's not from any superpower; she reports environmental and native Australian stories from the bush. She's never been to sea, but she's never met a language barrier she didn't like. These five weeks will test her as extreme deep-sea pressure tests Ocean Dragon and its diving scientists. No sub has ever taken three humans to full ocean depth. What will crack? Who might die? The deep sea remains a challenge to finding new life - and resources to extract. For the very first time, China opens its doors on its highest-risk mission of all.
