The Ninth Day is a 2004 German historical drama film directed by Volker Schlöndorff and starring Ulrich Matthes and August Diehl.

The film is about a Catholic priest from Luxembourg who is imprisoned in Dachau concentration camp, but released for nine days.

He returns to his native city, where the young SS officer Gebhardt tells him that he should convince his bishop to cooperate with the Nazis.

Gebhardt, himself a former candidate for the priesthood, tries to convince the priest that the role of Judas is just what God wants from him.

Kremer is confronted with a hard decision: Should he betray his Church or should he return to the concentration camp?
