For the people who wonder about it, the story is about an old Bolivian folk legend called El Tio, about a deaf child who escaped his abusive home and found a stray dog to keep him company. He had the power to heal people with his voice, and he found a man that was being stoned by the villagers. He sung to the man, and healed his heart. Afterwards, he found a man that was "different" and shunned by society. He sung to this person as well, and healed his spirit and mind. They went to a mine near the village, where a demon resided. The demon could control anyone who heard his voice and had put the village under his influence. While the dog and 2 men could not enter the cave, the boy was deaf and could not hear the demon. So he stayed behind and used his voice to be louder than the demon and overcame him, keeping the village safe. He had to stay there forever to sing to the demon and keep him away. ^^
