Founded in 1212, the St. Thomas Choir Leipzig is one of the most famous and prestigious boys' choirs in the world. This documentary, upon the 800th anniversary of the group's formation, accompanies "Die Thomaner," ages 9 to 18, over a period of one year at home and touring abroad. Their unique world, from motets to boarding school to a South American tour, is filled with pressure to perform, doubt pride, and homesickness, balanced by accomplishment, growth, and friendships that will last a lifetime.
