On a lonely homestead lives potter and musician Kristian Körting, who describes himself as "a musician from birth on" and "a musician searching for true sound." His love for music is the motivation for making his own organ. The pipes for the instrument are made out of clay, creating a uniquely ethereal and glassy sound.

The title refers to the infamous (and transposed) B-A-C-H motif that Körting plays on the organ.

This documentary records the process of creating the organ and Körting's first tries at playing the instrument.
