Michel Duchaussoy

On the night of 16 July 1942, ten year old Sarah and her parents are being arrested and transported to the Velodrome d'Hiver in Paris where thousands of other jews are being sent to get deported. Sarah however managed to lock her little brother in a closet just before the police entered their apartment. Sixty years later, Julia Jarmond, an American journalist in Paris, gets the assignment to write an article about this raid, a black page in the history of France. She starts digging archives and through Sarah's file discovers a well kept secret about her own in-laws.

Kurt Gerstein—a member of the Institute for Hygiene of the Waffen-SS—is appalled to discover that a poison gas he helped discover is being used to kill Jews. Driven by his conscience to alert the rest of the world, Gerstein teams up with a young Jesuit priest, Riccardo Fontana, but their protestations fall on deaf ears in the Vatican.
