The Chamber, from Emmy-winning cameraman Gavin Newman, documents the discovery and exploration of Sarawak Chamber in Borneo's Mulu National Park, the largest cave chamber yet found and the largest unsupported natural structure on Earth. Following the original explorers as they return three decades after its 1980 discovery, the film asks what it's like to be first into such a place, and how it can exist at all.

Why This Film Matters: Few frontiers remain truly unexplored, but the deep cave is one of them. The Chamber captures the awe and disorientation of standing inside a void so vast it defies comprehension, and honors the explorers who venture where light has never reached.
