The World's Biggest Cave

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?

Charging Back: A Rhino Story

This film uncovers the intriguing mystery of the return of the African rhino. In the 1800s there were more than 500,000 white and black rhinos in Africa. But by the 1990s, ivory poaching had left less than 7,000 animals alive. Remarkably, today their numbers have risen to 11,000. But there is now a new, deadly threat. Charging Back starts at the Pilansberg Game Reserve, where mysterious, unseen assailants were killing rhinos. Poachers could not be blamed, as the horns remained intact. Unexpectedly, the perpetrators prove to be relocated adolescent elephants, orphaned in culls. Lack of family structure has turned them into aggressive delinquents - a problem which conservation authorities now address by importing the steadying influence of older bulls. In astonishing scenes, the attackers are captured red-handed. Without the least provocation, elephants launch vicious assaults on unsuspecting rhinos.
