简介：Hang Sơn Đoòng was found in the deep jungle of central Vietnam. In this world's largest underground cave, there is a landscape and ecology as wonderful as its size. In 2014, when the Vietnamese government announced plans to install a cable car in the cave, it became the center of huge controversy. From the demand for environmental protection to the expectation that development will provide an opportunity to break free from poverty, the film follows the conflicts surrounding Hang Sơn Đoòng.
