Borneo has spent its entire existence, well over 100 million years, circling the equator. Consistent sunlight, warmth and rainfall means the perfect conditions for life. But it is the battle for those resources that makes Borneo one the richest regions on the planet. It fuels a bizarre realm of giant apes, tiny bears, plants that kill and jellyfish that farm. This film reveals a spectacular and diverse cast, as well as a behaviour never documented before – pied hornbills trying to hunt bats in flight. Borneo still has secrets to reveal.
