He reaches the final stage of his epic 650-mile journey, following the annual migration of Botswana's 130,000 elephants. Together with his guide Kane, Lev follows the elephants deep into the heart of the Okavango Delta, a vast wetland teeming with wildlife where every year more than 40,000 elephants gather to feed. Lev and Kane narrowly avoid a pride of lions who have brought down a male buffalo and watch as they move in for the kill, but are forced to wade through wide channels where crocodiles, hippos and snakes lurk.
They cannot tolerate sunlight; some of them are even blind. However they are one of the world's most ingenious builders: Termites. They build high-risers that are, relatively speaking, 25 times higher than the Empire State Building in New York. They are the only animals that have managed to build an air-conditioning system without electricity. Their nests are architectural masterpieces that rise up to eight meters from the ground and contain brood chambers for larvae, corridors for transportation and fungal gardens for nutrition. Termites - The Inner Sanctum takes us along a journey into another world. Visit the skillfully built termite mounds in the savannah, termite nests in the tropical rainforest with their colossal columns of termites foraging for food - and the termites that wreak terrible damage to wood-framed homes. Filmed in the US, Kenya and Borneo.

In this episode Brian uncovers how the stunning diversity of shapes in the natural world are shadows of the rules that govern the universe. In Spain he shows how an attempt by hundreds of people to build the highest human tower reveals the force that shapes our planet. In Nepal, honey hunters seek out giant beehives that cling to cliff walls. The perfect hexagonal honeycombs made by the bees to store their honey conceal a mathematical rule. Off the coast of Canada, Brian explains how some of the most irregular, dangerous shapes in nature - massive icebergs that surge down from Greenland and into shipping lanes of the Atlantic - emerge from a powerful yet infinitely small force of nature. Even the most delicate six-sided snowflake tells a story of the forces of nature that forged it.
The Maldives are the lowest country in the world-and getting lower, due to rising sea levels.

Asia - the most varied and extreme continent - stretching from the Arctic Circle to the equator. Walrus gather in huge numbers in the frozen north and brown bears roam remote Russian volcanoes. This is a world of the rarely seen, from yeti-like monkeys in the mountain forests of China to the most bizarre predator in the baking deserts of Iran. Asia is the largest of all continents but it seems there’s not enough space for wildlife. The deep jungles provide sanctuary for the last few Sumatran rhino.
