On the first leg of their journey, wildlife filmmakers Gordon Buchanan and Justine Evans set out to discover whether the mountains of western Burma are home to a population of Asian elephants that could prove critical to the survival of the species. Finding elephants in a dense bamboo forest is a challenge. Notoriously grumpy, Asian elephants are likely to charge if caught unaware. It is a race against time as the world eyes up Burma's natural riches - what the team finds could change the future of Burma's wilds forever.

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.

This episode details the relationship between flowers and insects. There are some one million classified species of insect, and two or three times as many that are yet to be labelled. Around 300 million years ago, plants began to enlist insects to help with their reproduction, and they did so with flowers. Although the magnolia, for instance, contains male and female cells, pollination from another plant is preferable as it ensures greater variation and thus evolution. Flowers advertise themselves by either scent or display. Some evolved to produce sweet-smelling nectar and in turn, several insects developed their mouth parts into feeding tubes in order to reach it.

Andrew Lincoln narrates a look at how animals adapted to the cold are struggling in a warming world. A snow leopard in the peaks of the Indian Himalayas is forced from his home by a rival male, while an Arctic ground squirrel in Alaska undertakes the coldest migration of any mammal, and a young Arctic fox in Svalbard must face her first winter alone.
