Sparked by the true story of Aya, a four-year-old Jordanian girl killed by her father because he believed her to be possessed, filmmaker Dalia Al Kury launches a fascinating investigation into a controversial and little-known aspect of Islamic culture: belief in djinn. The djinn are believed to be supernatural creatures that occupy a parallel world to ours and their emergence is associated with sexuality, political unrest, poverty and mental illness. The taboo subject of demonic possession remains broadly unresolved in the hearts and minds of some Muslims due to its complex and uncomfortable nature. Using a subjective, “undercover” style, Al Kury journeys into the obscure world of exorcists and the possessed, confronting their traditions and rituals. It makes for a telling ghost story that bares the filmmaker’s and her society’s subconscious underbelly.
