There are evidences of global warming everywhere in the world. Chacaltaya, Bolivia is also one of the places with the evidences. It used to have the highest ski resort in the world, but it is a bare mountain as snow has melted since 2000. Samuel Mendoza is the first witness. He was a lift manager at the resort, but now he has to greet climbers not skiers. While talking about the past of Chacaltaya, which used to be covered with snow, he expects that it will snow someday again. This documentary chases Samuel and warns us through a man
 who lost all of his life due to the change in nature. It tells us that the earth gradually becomes an uninhabitable place and it is not only Samuel but all of us who are in danger. Will it snow there again? Samuel in the Clouds shows that the problem is not so simple that we can solve it just with ardent wishes.
