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.

Liz Bonnin introduces a cast of charismatic animals to reveal the remarkable strategies they use to survive, and even thrive, in winter. For animals this is the toughest time of year, and preparations start early. In autumn, Siberian chipmunks collect food in their cheek pouches to stockpile in their burrows, while caribou make an epic journey to new feeding areas away from the worst weather. With the arrival of winter, the American bobcat has to find its prey beneath deep snow, while an Arctic fox must sniff out its very own frozen ready meal. A sea otter mum keeps her cub warm by blowing air into its coat, while some animals turn white to blend in with the snowy world around them. As winter begins to loosen its grip, an Arctic ground squirrel stirs from an eight-month hibernation and has to woo its mate in just twelve hours, and baby animals emerge to play in the snow before spring's imminent arrival. Along the way, Liz meets some of our most iconic winter animals to uncover the secrets behind their seasonal success stories.

The great mountain ranges are some of the planet's most spectacular landscapes, but they are unforgiving places to live in, and only a few animals have what it takes to live at extreme altitude. Mountain animals are amongst the most elusive in the world, and this film provides unique and intimate glimpses into their secretive lives. Witness the moment four snow leopards come together when a mother and cub become trapped between two rival males. Join grizzly bears as they dance against trees to rub off their winter fur and soar with golden eagles hunting amongst Europe's snow-capped peaks.

Steve Backshall leads a team of elite explorers - including world leading underwater cave explorer Robbie Schmittner, former Royal Marine Aldo Kane and diving camera operator Katy Fraser - into the wilds of the Yucatan Peninsula in Mexico. Under the vast jungle here is the largest unexplored network of caves in the world, comprising thousands of kilometres of passageways. They are stunningly beautiful but incredibly dangerous - much of the system is under water. First the team must trek through tough, scorpion-infested jungle to camp alongside a giant sinkhole in the jungle floor - a dark gateway to an underworld full of nightmarish creatures.

In the last 30 years the world's urban areas have almost tripled in size, changing at a rate wildlife has never experienced before. As cities are built, animals are pushed out of their natural homes. Their stories are the most surprising and captivating of all. Today, these 'wild outcasts' find themselves fighting for their place in a land that once belonged to them. In this episode we feature elephants in Sri Lanka and see that competition between them and humans for land and resources is resulting in deadly territorial conflicts, which demand solutions. And on the Pacific coast of Costa Rica we meet a troop of capuchin monkeys and learn how our behaviour is affecting them, and raising big questions about their future. But we also discover where we learn to live with wildlife as neighbours, and give it the space and resources it needs, it can thrive. The resulting relationships between human and animals can be mutually beneficial. We meet an Amsterdam heron called Kiri who has been visiting the same house twice a day for the last 17 years, befriending its owner, and the Florida manatees whose population has recovered to such an extent under the guardianship of local human residents that, in recent years, they have been taken off the endangered species list, and contributed to a massive boom in the local tourism industry. We meet the swiftlets who have evolved to live only in people's houses and specially built swiftlet hotels in Indonesia. And the surprising story of a population of tiny foxes on a Californian island whose presence benefits the hardened military personnel of a US naval base. This hopeful but realistic episode culminates with the return of charismatic ocean giants to the world's most iconic city, as humpback whales breach against the New York skyline.
