Chapter One: The Kiteboard Legacy Begins

In 2009 a team of British cavers went on an expedition deep within the jungle of central Vietnam. To their amazement they discovered an enormous cave which they believe to be the biggest in the world. The team, the first humans ever to enter the cave, traveled 6 kilometers underground until their way was blocked by a gigantic rock face they dubbed 'The Great Wall of Vietnam'. Now they have returned, but this time with the right equipment to climb the wall and with a geologist and zoologist to discover if this is indeed the Biggest Cave in the World and what secrets lie deep within?

A group of scientists are thinking outside the box for ways to reverse the effects of global warming.

You have to go deep underground, along a winding path. You will crawl in the mud and in the cold, in your own sweat, which after a while will freeze on your skin. You will go from light to darkness to rediscover the light, the light in yourself... The first part of the three-part documentary series about exploring the underground in Slovakia will guide you through a tangle of incredibly narrow passages and at the same time a number of spacious underground halls of little-known caves. It introduces you to the admirable people to thank for discovering the underground riches beneath our feet. Rocky Stream, Štefanová, Eternal Robot, Cave of Dead Bats, Old Castle, Moon Shadow.
