A story that begins 3.5 billion years ago, fungi makes the soil that supports life, connecting vast systems of roots from plants and trees all over the planet, like an underground Internet. Through the eyes of renowned mycologist Paul Stamets, professor of forest ecology Suzanne Simard, best selling author Michael Pollan, food naturalist Eugenia Bone and others, we experience the power, beauty and complexity of the fungi kingdom.
