Jadav Payeng has spent decades planting trees alone on Majuli, a river island in India's Brahmaputra that erosion and sandbars had turned into wasteland. Starting in the 1970s with saplings pushed into bare sand, he has built a forest now larger than New York's Central Park, dense enough to draw elephants, deer, and birds back to ground that once supported nothing. The film follows him through the trees he raised, letting him talk plainly about why he kept going year after year with no institutional backing and little recognition until journalists found him. He comes across as practical rather than mystical about the work, describing it as a response to a specific problem, a shrinking island, rather than an environmental crusade. Footage moves between the density of the current forest and what the land looked like before, making the scale of one man's labor legible without narration doing the explaining. The soundtrack is original, but the forest itself carries the film.
