Der neunte Tag / The Ninth day - by Volker Schlöndorff (2004)

A drama loosely based on Jean Bernard's Nazi-era prison diary.
In World War II, after a period living hell on earth in the concentration camp of Dachau with other catholic priests, Father Abbé Henri Kremer gets a nine days leave to return to his home town for his mother's funeral. Along this period, the SS Gestapo lieutenant Gebhardt tries to persuade Henri, who was born in silver-spoon and member of an influent Luxembourgian family, to convince the local bishop to give-up resisting to the Germans and write a letter to the Vatican in the name of the Catholic Church of Luxemburg convincing the Pope to support Hitler and the Nazi regime. The ambivalent Henri questions himself and the bishop what he shall do.
