We know so little of the world beneath our feet. To most it is a place only of fear and darkness, though to a brave few it is one of knowledge and wonder to be found nowhere else.

Based on the bestselling book by Robert Macfarlane, Underland is a cinematic documentary that voyages into worlds rarely glimpsed by human eyes. Beginning in the shallow soils beneath an old ash tree, he film follows several ‘astronauts of the underworld’ as they travel into ancient sacred caves, flooded storm drains, melting glaciers, underwater burial chambers and a deep underground laboratory built to solve the mysteries of the Universe.

Narrated by Oscar-nominated Sandra Hüller, and with a uniquely poetic approach, Underland is a deep dive into the Earth that ultimately presents a groundbreaking vision for rethinking our lives on this fragile surface.
