“Amazonia” is a 3D adventure film set in the vast expanse of the Amazon rainforest, the largest of its kind on Earth. The story follows Chestnut, a Capuchin monkey who has been domesticated but ends up surviving a plane crash, leaving him stranded in the thick jungle. Alone in this unfamiliar environment, he must adapt to a life of freedom amidst a diverse array of wildlife, including jaguars, alligators, snakes, tapirs, and hawks. Over time, Chestnut learns to navigate his new surroundings and forms bonds with other creatures, particularly Gaia, another monkey of his species.
