Humanity would not exist without trees. They are the backbone of the biosphere, fertilizing the earth, regulating the climate and water cycles, indispensable to our survival on earth. But just as science is starting to understand the true importance of this little-known genius, its very existence is menaced by man-made disruption. This film provides a science-based exploration into the superpowers of trees, a first-of-its-kind journey below the surface, to better understand them, and also the challenge that we face together in the struggle against global warming – a journey into a new dimension.

An epic documentary film that sends nine scientists to extraordinary parts of the world to uncover unexpected answers to some of humanity’s biggest questions. How did life begin? What is time? What is consciousness? How much do we really know? By introducing researchers from diverse backgrounds for the first time, then dropping them into new, immersive field work they previously hadn’t tackled, the film pushes the boundaries of how science storytelling is approached. What emerges is a deeply human trip to the foundations of discovery and a powerful reminder that the unanswered questions are the most crucial ones to pose. Directed by Emmy-nominated and Peabody Award-winning filmmaker Ian Cheney and advised by world-renowned filmmaker Werner Herzog, The Most Unknown is an ambitious look at a side of science never before shown on screen.
