South America - the most species rich continent on Earth. From the volcanoes of the Andes to the world’s largest rainforest, the Amazon, animals here must specialise to carve out a niche. In Patagonia, a puma mother draws on a lifetime’s experience to catch prey three times her weight. In the cloud forest, rarely seen Andean bears clamber thirty metres into the canopy to find elusive fruit. Poison dart frogs use ingenious methods to keep their tadpoles safe, whilst anacondas stalk capuchin monkeys. At Igauzu, swifts make death-defying flights through one of the biggest waterfalls on Earth.

Humans, octopi and pine trees alike are all made up of cells, tiny but sophisticated systems that keep life going. Cells are almost like tiny factories run by robots, with the nucleus, DNA, proteins, lipids, and vitamins and minerals all playing critical roles. George Zaidan and Charles Morton lay out the blueprint of a cell and explain how biochemistry binds all life together.

For the last decade, a team of frontline medics has been fighting to save Borneo's critically endangered orangutans. Armed with cameras, International Animal Rescue has documented their struggle: pulling apes from devastated jungle, giving emergency medical care, rehabilitating and releasing the healthiest orangutans back into the wild. This is both the story of their life-saving work and of how one of our closest wild relatives has been pushed to the brink of extinction. Combining genuine rescue footage with contributions from experts throughout, this documentary looks toward the future and asks what hope remains to save the orangutan.

In an effort to outwit raccoons, are we pushing their brain development and perhaps even sending them down a new evolutionary path? Using high-definition, infrared cameras that turn pitch dark into daylight; we take viewers deep inside a world that was once shrouded in mystery – to gain new insights and understanding about a species that is far more elusive and wily than most people ever imagined. “There is a lot we don’t know, and the more we’ve looked at raccoons, the harder they are to understand.” — Stan Gehrt, Wildlife Biologist & Internationally recognized raccoon expert

The final programme looks at the superorganisms formed by bees, ants and termites. Attenborough reveals that their colonies, whose individuals were once considered purely servile, are "full of conflict, power struggles and mutinies." They evolved when such creatures moved away from a solitary existence and started building nests side-by-side, which led to a collective approach to caring for their young.
