It is a nightmare that has stalked us for centuries: hordes of human beings transformed into mindless, cannibalistic monsters. Could this civilization-ending nightmare become reality? Scientists have discovered pathogens that turn insects into the walking dead. New strains of viruses are attacking humans every day. Mathematicians have calculated the likelihood of surviving a zombie virus outbreak: they’re not hopeful. Now neuroscientists are discovering how easy it is for us to lose conscious control of our bodies. Are we at risk of becoming puppets? If we were in the middle of a zombie apocalypse, would we even know it?

In Africa's ancient south west corner, two extraordinary deserts sit side by side. Water is in short supply, yet these deserts are somehow full of life because the creatures that live here have turned the rules of survival on their head. This film celebrates nature's ingenuity, no matter how tough it gets. In the Kalahari scrublands, clever meerkats are outsmarted by a wily bird, solitary and belligerent black rhinos get together to party and giant insects stalk huge flocks of birds. Rain almost never falls in the Namib - instead it must make do with vaporous, vanishing fog. The creatures in this, the world's oldest desert, have gone to the extremes, as spiders wheel to escape and a desert giraffe fights to defend his scant resources in the greatest giraffe battle ever filmed.

Written and presented by David Attenborough, who said: 'One of the most wonderful things about filming plants is that you can reveal hidden aspects of their lives, you can capture the moment as one plant strangles another, and as they burst into flower. But whilst time-lapse photography allows you to see things that no human being has ever seen before". David begins his journey inside the magnificent Palm House, a unique global rainforest in London. Here, he explores the extraordinary plants that are so well adapted to wet and humid environments and unravels the intimate relationships between wet zone plants and the animals that depend on them. It was in the wet zones of the world that plants first moved on to land and in the Waterlily House David reveals how flowers first evolved some 140 million years ago. Watching a kaleidoscope of breath-taking time-lapses of these most primitive of flowers swelling and blooming in 3D, he is able to piece together the very first evolutionary steps that plants took to employ a wealth of insects to carry their precious pollen for the first time. David discovers clues to answer a question that even had Charles Darwin stumped: how did flowering plants evolve so fast to go on to colonise the entire planet so successfully?

Bladderwort utricularia is a pond-dweller that is among the fastest known, its traps snapping shut in less than a millisecond. As the seasons change, David demonstrates how plants operate on a different time scale to us; how they modify their lives according to the time of year. We discover insects’ hidden links with plants, both as pests and pollinators. UV-sensitive 3D cameras reveal the invisible alter-ego of plants and their flowers’ mesmerizing patterns; a parallel-dimension of strange colours and stunning patterns through which plants communicate with them. With the aid of visual effects, David steps among the swirling vortices of plant scent; communication signals with which plants are inextricably plugged in to the natural world. And using a tuning fork, he demonstrates how plants and insects can even communicate with music. As autumn envelopes the Gardens, fungi reveal themselves not as the enemies of plants but their vital allies. In Kew’s atmospheric Fungarium, David discovers a specimen that has the power of mind control and another that lives underground where it has grown to be so big it can be counted as the largest single organism on the planet. It is 6 times bigger than Kew Gardens itself.

The world of bugs normally passes beneath our notice, yet shrink yourself to their size, see them in 3D and you’ll enter a world you’d never believe existed. Big Bugs in 3D uses specially developed 3D technology to take the viewer on a global journey, from Mexico and the rainforests of Asia to our own backyards. There are perhaps four and a half million different kinds of bugs sharing the planet with us. They exist in a bewildering variety of forms, some more like creatures from an alien world. Big Bugs asks how and why these creatures have become so successful.

In this documentary we will be transported into the world of ants. What animal has achieved immortality? What animal is the most warlike? What animal has the greatest supercity on the planet? Not man but ants. They are the real success story. It is only their tiny size and our vanity that allows us to hold onto the myth of our supremacy. Ants rule the planet. They are found in more habitats from far northern Finland to the sweltering tropics. The largest colony known of these insects is in Japan, where 306 million ants, with 1 million queens, in 45,000 colonies spread over 270 hectares. The fiercest warriors on earth are the slave maker ants. Other ants have barracks and sentry posts to protect themselves against surprise attack.
