Imagine being transported to a place with humidity above 90%, with more diseases than anywhere on Earth, and where every breath draws a cloud of insects. Charlotte Uhlenbroek takes up the challenge in this exploration of the world's rainforests. All the jungles are very different. On each continent the same niche is occupied by a different species - Spider Monkeys in South America and Gibbons in South East Asia. Charlotte compares the situations she finds in each jungle together with the solutions the creatures in each have adopted to survive. Many individual films have been made about rainforests, but no one has ever attempted a global look at them on this scale. A combination of sheer adventure and the latest technology enables the viewer to experience the planet's most complex terrestrial habitat in all its glory.
