Snowboarder Jeremy Jones and a crew of riders travel to Japan, Bolivia, and Norway to look at the trees that make backcountry snowboarding possible: the gnarled, wind-bent conifers that grow right at the edge of where trees can survive. Interviews with foresters, indigenous elders, and scientists explain how a tree's rings record centuries of drought, fire, and changing snowpack, turning old-growth forests into a kind of archive. In Japan the crew rides through snow-laden birch groves shaped by lake-effect storms; in Bolivia they meet communities whose queñoa forests, the highest-altitude trees on Earth, are shrinking under warming temperatures; in Norway they trace Sami reindeer herders whose culture depends on the same treeline ecology. Riding footage alternates with quiet shots of bark, root systems, and cross-cut trunks, framing the mountains less as a playground than as a living system under strain. The film's case is straightforward: the trees that give these places their character are also an early warning system, and their rings are already writing that story down.
