In 1831, the Strasser family, from Laimach in the Zillertal valley, made their way to Leipzig in Germany, where four of Strasser children performed "Stille Nacht" outside Austria for the first time. From there, the carol has made a triumphal march all over the world. One hundred and eighty years later, it has been translated into more than 300 languages and acknowledged as intangible cultural heritage by UNESCO.
This documentary retraces the Strassers’ arduous journey, shooting in locations including Leipzig and the small Strasser house in Laimach. Four amateur actors and singers from the Zillertal valley play the Strasser siblings. Their voices are impressive.
