The video is based off of the Bolivian Legend, El Tio. I think. It's about a deaf boy who escapes his abusive home and sets off on an adventure. Along the way he meets a stray dog, a man being stoned by the villagers, and a man who is "different" and is rejected by society. The eventually find the cave of the El Diablo (the devil) in the desert. Only the boy can enter because he cannot hear El Diablo's influence. If the others try to enter they will be influenced. The boy stays in the cave to drown out the voice of the devil with his own, so no one will be influenced by El Diablo. Hopefully this helped.
