In the heart of the Atlantic, Gordon Buchanan joins a team looking to discover why huge numbers of devil rays, fish with 'wings' nearly four metres across, and gather every summer near the Azores archipelago. In northeast Turkey the on-board cameras are carried by brown bears as part of a study trying to understand why so many bears survive in a small patch of forest. In southern France on-board cameras help scientists trying to prove that guard dogs can help protect sheep flocks from wolf attacks. The night-vision cameras show how the dogs work together as a team to fend off the wolves.

This special, narrated by Andrew Scott, celebrates the drama of Autumn and how animals and plants deal with the new challenges it brings. This is the time of year that brings the world's most spectacular transformations. With winter fast approaching, life has to get ready and that means feeding up while you can, fighting for the last chance to breed and rushing to grow up before the cold returns. While chipmunks and beavers dash to stash their winter supplies, many animals from musk oxen to beetles have to battle for mates and young gannets must face life's first dangerous challenges.

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.
