In the beginning of the 19th century, Johannes Elias Alder is born in a small village in the Austrian mountains. While growing up he is considered strange by the other villagers and discovers his love of music, especially rebuilding and playing the organ at the village church. After experiencing an "acoustic wonder", his eye color changes and he can hear even the most subtle sounds.
