The terrorist attacks of September 11, 2001 sent the world into a state of shock. Yet some had been loudly and publicly warning of the dangers posed by terrorism. Ahmad Shah Massoud, an Afghan Mujahideen commander, was among them.

The friendship between Christophe de Ponfilly and Commander Massoud, a legendary figure of the Afghan resistance against the Soviet invader, goes back to the filmmaker's first film, "A Valley Against an Empire", made in 1981. Fifteen years later, weakened, isolated, betrayed by many of his own, the "Lion of Panshir" has not surrendered to his new and implacable enemies, the Taliban. While preparing his next offensive, he evokes his commitment and his fights, and bears witness to a history in which he has been one of the main actors for twenty years. At the same time, the director questions the role and power of the media, as well as his own approach as a filmmaker. Commander Massoud was killed in an attack in September 2001.

When the Soviet troops entered Afghanistan in December 1979, Christophe de Ponfilly and Jérôme Bony made their first clandestine reportage in the Panjshir valley. "A valley against an empire" testifies to the beginning of the struggle of a young commander, Amah Shah Massoud.

According to the official history of Afghanistan, ruthless destruction has always prevailed over art and creation; but there is another tale to be told, the forgotten account of a diverse and progressive country, seen through the lens of innovative filmmakers, a story that survives thanks to a few brave Afghans, a small but very passionate group that secretly fought to save a huge film archive that was constantly menaced by war and religious fanaticism.

On September 9, 2001, Commander Massoud, a hero of the Afghan resistance, was assassinated by two members of al-Qaeda posing as journalists. Two days later, the terrorist organization struck the United States. However, a few months earlier, during a visit to France, Commander Massoud had come to warn the West about the disastrous plans of al-Qaeda and the rise of the Taliban. He asked the West to exert pressure on Pakistan, a country that supplied arms, supported and sheltered the Taliban, but which was also a major buyer of French arms. He was not listened to.
