Director Matthew Heineman returns with another immersive documentary from the front lines of one of the most dangerous places on Earth. In City of Ghosts, Heineman focuses his camera on the heroic citizen-journalists of Raqqa is Being Slaughtered Silently (RBSS), who take great risks in order to document Islamic State atrocities in their home city. While the work of RBSS has attracted international media attention, the stories of the individuals behind it, their lives and their personal strength through adversity, provide a unique perspective on the ongoing Syrian conflict. City of Ghosts also offers a captivating window into the media war being fought between ISIS’s propaganda team and the RBSS journalists, as it follows the perilous journey of RBSS members as they continue their work, even in the face of insurmountable odds.
