The mountaineer and filmmaker Rafael Pease organizes a winter expedition to the 6,570 m Tupungato volcano, located in the Chilean Andes. The idea is to promote the creation of a national park in an important area for biodiversity and essential to supply water to 40% of the country's population. In a context of the Chilean people's struggle for their social and environmental rights, the documentary exposes a network of corruption between the government and multinationals.
