Up on the Mountain is a documentary film that follows Southeast Asian refugees, Latino immigrants, and rural Americans on a year-round migration to harvest wild mushrooms in the American west. Working on foot in public forests, equipped with only a bucket and a pocket knife, mushroom picking is an accessible way to become their own bosses. But despite evidence of the sustainability of the harvest, the workers who supply the restaurants and markets of Europe, Japan, and North America are repeatedly denied access to public lands by racist and classist policies.
