he powerful true story behind the most popular Christmas carol of all time. In 1818, when Joseph Mohr is assigned to be the new assistant priest in Oberndorf, a small Austrian town near Salzburg, the young man is full of ideas and ideals. His passion to bring the church closer to the common people sets him on a collision course with his superior, Father Noestler. When Mohr organizes a church choir that includes outcasts from the local tavern and performs in German instead of Latin, Noestler threatens him with disciplinary action. The night before Christmas, Mohr has to decide if he will accept defeat and leave Oberndorf or embrace the true significance of the Holy Night.
