Based on true events following the end of WWII in Berlin.

In the course of the Allied denacification initiative a US Army major is given the task of investigating whether the world-renowned conductor Wilhelm Furtwängler had collaborated with the Nazis. Trusting in the purifying power of music, the sensitive artist had decided to stay in his hometown despite the risk of having to come to terms with the totalitarian Nazi regime – a tricky manoeuvre in the thicket of moral ambivalence. To find his own truth the major goes to extremes, his black-and-white philosophy, however, proves inadequate for making the right accusations.
