L'Origine de la violence (2016)
Directed by Élie Chouraqui

Film Synopsis

During a trip to Germany, Nathan Fabre visits the concentration camp at Buchenwald and happens upon a photograph in which he vaguely recognises a face in the background.  The face bears an uncanny resemblance to that of Nathan's father, so on his return to France he feels compelled to broach the subject with his father, Adrien, over dinner.  At first Adrien is reluctant to say anything on the matter, but his son's persistence forces him to affirm what Nathan already knows.  The man in the photograph is his own father, one of the unfortunates who was sent to Buchenwald during the Second World War.  Determined to find out more about the fate of his grandfather, Nathan undertakes his own investigation and uncovers a tragic episode that his family are understandably keen to forget...
