In the musical road movie, New Zealand musician Hayden Chisholm sets out on a journey of discovery across Germany in search of German folk music. As a stranger with an unbiased view of German culture and an open ear for the lyrics and melodies of modern and traditional musicians, he encounters a lively diversity of regional customs and activities. In Sound of Heimat – Deutschland singt, directors Arne Birkenstock and Jan Tengeler also shed light on the ambivalent attitude toward folk music and the understanding of one's own homeland that is so widespread in Germany. These are topics that have been forgotten in many places due to past ideologization and the "ideal world" of the Musikantenstadl.
