As a direct response to the November 2015 attacks on Paris, France launched a military campaign against the Islamic State. That fight, and the "year of terror" in France, began a year ago with the attack on Charlie Hebdo, a satirical magazine. Five-time Bafta-winning director Dan Reed uncovers the untold story of the slaughter and the first strike by the Islamic State in Paris, which occurred at a Jewish grocery store, using unprecedented access to the French authorities and previously unseen material. The dramatic attacks and the tremendous manhunt that gripped the world for three amazing and terrible days are pieced together through the first-hand accounts of key witnesses, police officers, and survivors.
