The blood orchid - a rare flower that could hold the secret of eternal life and be worth a fortune to the company that finds it first. Led by a pharmaceutical research team, a scientific expedition sets out to go and explore deep into the jungles of Borneo to locate and bring back samples of the legendary plant. Battling through rainstorms to make their way upriver, the group encounters poisonous insects and a ferocious crocodile, only to discover they're being stalked by an even greater danger: a gathering of giant anacondas. Heat-sensing, fifty-foot-long flesh eaters that will go after anyone that crosses in their path.

Bacteria, viruses, but also fungi, algae, pollen, and even insects: micro-organisms thrive and circulate constantly in our sky. How can so many living beings find their way into the air and circulate? How do they survive? And what influence do they have on our lives and the living world? Biodiversity, health, climate: it is only recently that scientists have begun to understand how this discreet aerial "plankton" affects our lives and our ecosystem. But despite their many virtues, some of these micro-organisms are now threatened by human activities. With the help of experts and 3D models, this scientific investigation plunges us into the heart of a still mysterious world, and reveals the diversity and fragility of the air we breathe.

An innovative documentary that illustrates how weather works by performing brave, ambitious (even unlikely) experiments that show how nature transforms simple ingredients like wind, water and temperature into something spectacular and powerful.
