Deep within the arid expanse of the Kalahari Desert lies a true anomaly of nature: a land shaped by the unstoppable flow of inland floods to create one of the greatest wildlife havens in Africa. Experience the life-giving might of the Okavango Delta, in all its lush beauty.
Cameras travel to the Arctic and Antarctic circles, following chicks in a king penguin colony on the island of South Georgia in the Southern Ocean. On the other side of the world, Spy Walrus discovers a walrus family hauled out on an ice floe, before Spy Gyrfalcon follows the family as they head towards dry land. Elsewhere on Norway's Hornoya island, Spy Puffin follows thousands of male puffins as they gather in the snow and search for their life-long partners.
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.
