Much of life on Earth is connected by a vast, hidden network that we are only just beginning to understand. Out of sight, between the world of plants and animals, another world exists – the kingdom of fungi.

Through the eyes of passionate biologist and writer Merlin Sheldrake, join us on this brilliant round-the-world journey into the secret world of fungi. Through dazzling images of fungi under the microscope, and all around us in the forest, Merlin unravels the many secrets of these essential organisms in the web of life. So much more than mushrooms, not only do fungi shape the weather and support life on land, they are at the cutting edge of medical research and even have the power to break down plastic waste.

Narrator and iconic artist Björk, takes us from the ancient Tasmanian Tarkine rainforest to the mystical wilds of China's Yunnan Province, in search of solutions to some of our planet's biggest challenges. Can the answers be found in the wonderful world of fungi?

We are just starting to understand how important fungi are to life as we know it and how critical they are in protecting us from the impacts of climate change. Yet of the estimated 2 – 11 million species scientists think exist we have only described around 150,000 of them. It is a neglected and new frontier of scientific discovery.

Now the push is on to document as many species as possible, as fast as possible.
Many new species are found by renowned fungi hunter and photographer Stephen Axford, who with filmmaker Catherine Marciniak, also creates exquisite time-lapses of fungi growing. In one of the wettest years on record in Australia, Stephen and Catherine followed in the path of the rain to document the fungi that emerged. Their mission – to find out how fungi fit into the world of living things.

It is an exploration of the world of fungi as you have never seen it – combining a decade of research and passion, Stephen and Catherine's mesmerizing fungi time-lapses and footage, and the most incredible fungal stories.

This fungi adventure takes us into some of the oldest landscapes in Australia, to explore the critical role fungi play on earth and how they can help humans in the fight against climate change. It includes a journey into the world of zombie fungus hunting, a dig into the hidden trading deals between fungi and trees, a 10-year investigation to name a new species and an exposé of the rain-making fungal life of a desert.
The audience also goes behind the scenes into Stephen and Catherine's world of fungi photography and time-lapse, sharing in their discoveries along the way. It's a pioneering fungi safari with breath-taking imagery that unearths the foundation of life down under.
