Groundbreaking documentary which follows a Japanese-led team of scientists as they attempt to shed light on the mysterious world of deep sea sharks. Only 50 specimens of the newly discovered 'megamouth' have ever been sighted. Over four years, scientists and film crews voyaged in midget submarines into the depths of Suruga Bay and Sagami Bay to film them. Prehistoric 'living fossil' sharks such as bluntnose sixgill sharks, goblin sharks and frilled sharks also lurk in the bay. As part of the investigation, a sperm whale carcass was placed at the bottom of the bay to attract these sharks, which were then studied and observed from the submersible vessels. Revealing in detail the previously unknown behaviour of deep sea sharks, the film unravels another of the intriguing mysteries of our planet's biodiversity. Narrated by David Attenborough.

For the last leg of their journey, the team search for the most iconic animal of them all, the tiger. To find it, they must split up. Wildlife camerawoman Justine Evans and the science team head to the tangled jungles of northern Burma, one of the largest swathes of unbroken forest in Southeast Asia. Wildlife cameraman Gordon Buchanan heads to the only other place in Burma where tigers may still exist, the far south. The forests of Karen State were once home to a thriving population of tigers, but this region has been isolated by war for over 60 years and little is known about the fate of the animals. The team must overcome intense physical hardship and tough field conditions to find the evidence they need to help preserve this unique and largely untouched wilderness. What they discover could change the future of Burma's forests forever.
