For the first time in over 50 years, a team of wildlife filmmakers from the BBC's Natural History Unit and scientists from the world renowned Smithsonian Institution has been granted access to venture deep into Burma's impenetrable jungles. Their mission is to discover whether these forests are home to iconic animals, rapidly disappearing from the rest of the world - this expedition has come not a moment too soon.
On the second leg of their journey, wildlife filmmakers Gordon Buchanan and Justine Evans, along with a team of scientists, head deep into the mountains of western Burma. This is where they hope to find the shy sun bear and two of the world's rarest and most beautiful cats: the Asian golden cat and the clouded leopard.
Meanwhile, zoologist Ross Piper and the science team are on a mission to create a wildlife survey to present to the government of Burma to persuade them that these forests are so unique they must be protected. High on the forest ridges, Gordon finds evidence to suggest that Burma's wildlife might be in danger. Undercover filming in a border town known as the 'Las Vegas of the jungle' leads to a shocking discovery.
