Since the dawn of time, humankind has felt the need to explore, whether through terrestrial, subterranean, underwater, or space exploration. This film follows the attempt to connect the Fromagère chasm with the legendary Berger chasm, located in the Vercors massif. The exploration is undertaken by Cédric Lachat, a former world climbing champion, and David Parrot, a highly motivated speleologist. From preparation to success or eventual abandonment, this adventure explores the various facets of speleology: sport, science, and heritage.

In the village of Ruraï, in Papua New Guinea, people tell of a water hidden deep within the Nakanai Mountains so pure that anyone who drinks it is said to gain extraordinary powers. Immersed in the heart of a tropical rainforest, a team of cavers including the inimitable Cédric Lachat, set out to uncover this mysterious underground river system.
