Without explanation, Father Henri Kremer, a dissident Catholic priest interred at Dachau, is released from the living hell of the Dachau "Priest Block" and returned home to occupied Luxembourg. Reunited with his sister and brother, Kremer learns that his freedom is temporary. Gestapo Untersturmfuhrer Gebhardt, a lapsed seminarian, has arranged a nine day reprieve during which Kremer is expected to persuade the staunchly anti-Nazi Bishop of Luxembourg to capitulate to Nazi occupation and drive a wedge between Luxeumbourg and the Vatican. As Kreme resists, Gebhardt's threats turn increasingly pointed. Torn between duty, faith, the terror of returning to Dachau and fear for the safety of his sister's unborn child, in just nine days Father Henri Kremer must find a way to his ease his conscience, protect his family and save his soul without giving in to Gebhardt. But as the ninth day draws near, devout priest and zealous Nazi discover they have more in common than they realize.
