Calm at Sea (2012)

October 1941. Eighteen months into France’s occupation by German troops, young Communist members of the Resistance shoot dead an officer of the German Army. In retaliation, Hitler demands the deaths of 150 Frenchmen, as 'retribution'. The targets are to be mostly young men believed to share the assassins’ political convictions. Most of these men are taken from an internment camp for opponents of the occupation; a 35-year-old French rural administrator is ordered to select the victims. Although the parish priest appeals to their conscience and moral sensibilities, both the German military and their French helpers slavishly follow their orders.
