A CRACK IN THE MOUNTAIN is a feature length documentary which tells the story of the world’s largest cave.
Hang Sơn Đoòng which translates as “mountain river cave”, is located in the Phong Nha-Kẻ Bàng National Park in Quảng Bình Province in Vietnam. The national park is also a UNESCO world heritage site.
First found in 1990 by a local farmer, it wasn’t explored until 2009 when a British expedition team rigged ropes and descended down.
Many people have described Sơn Đoòng as a lost world. It has its own lake, jungle and even a unique weather system.
In 2014 plans were announced to build a cable car into Sơn Đoòng.
With many arguing that this would destroy the cave’s delicate eco-system and the local community divided over the benefits this development would bring, the film follows those caught up in the unfolding events.
The documentary also uses the narrative as a lens through which to investigate related themes such as the challenges of modern day exploration, environmental conservation & sustainability, and the perils of operating as an activist in a country such as Vietnam where freedom of speech is severely curtailed.
