The Ninth Day is based on the true story of a Luxembourger priest (Henri) who is sent to Dachau concentration camp (among thousands of other priests in WW II) for standing against the Nazi regime. The film brilliantly contrasts the hell of the concentration camp with making a deal with the devil (i.e. the Nazi regime that sent him there) once Henri is "freed" to return home. Some very weak-minded individuals will call this film "propaganda", since it accurately portrays the persecution of the Catholic church (both the clergy and the laity) under the Nazi regime rather than the historical revisionism which was popularized by the communist bloc over the last few decades. Not for the faint of heart (there is very graphic brutality throughout), it is definitely worth watching as both a time-capsule of life during occupied countries during the Nazi regime as well as a wake-up call to future generations.
