In the documentary O rio sobe a serra, director Raffaella Rosset takes viewers on a visually stunning journey into the heart of the Brazilian Amazon, exploring the intimate relationship between a remote riverside community and the river that defines their existence. The film follows local residents as they navigate daily life along the waterway, their traditions and livelihoods intricately woven into the ebb and flow of the currents. When seasonal rains cause the river to rise, flooding the landscape and reshaping their world, the community must adapt to the changing environment, facing both the beauty and the peril of their natural surroundings. Through observational storytelling and breathtaking cinematography, the documentary captures the resilience of these individuals as they confront the encroaching waters that threaten their homes and way of life. Blending elements of environmental cinema with human-centered portraiture, Raffaella Rosset crafts a meditative and deeply respectful portrait of a people living in harmony with one of the planet's most vital ecosystems.
