In October 2018, a European intelligence services informer entrusted Kamal Redouani, a leading reporter, with the GPS coordinates of the living quarters of French jihadists in Syria. This will be the first stage of a film that will provide a better understanding of the journey and life, under the Caliphate, of Western jihadists and their families who left for Syria. This work is urgent. In a country in ruins, the evidence left by Western jihadists is disappearing. And without evidence, there can be no justice.
