A team of excavators restoring Notre Dame makes a stunning discovery beneath the floor of the cathedral…an unmarked sarcophagus. When CIA operative Ridley Samaras and her new partner Henri are sent to investigate the strange finding, a vengeful creature is unleashed on the city. Part of a clandestine CIA unit that tracks arcane relics around the world, the operatives discover a chilling secret stretching back nearly a thousand years: the Knights Templar were imprisoning malevolent Middle Eastern spirits called jinn. The jinn that escaped from this sarcophagus is on a mission to free its demonic masters from captivity…masters whose power would devastate the earth. Ridley and Henri race after the jinn, from Portugal to Syria to England and Egypt, battling a radical remnant of the Templars seeking to exploit the supernatural chaos. As the partners trace the creature's path to unleash its final terror, they must prevent a global cataclysm at the most explosive place on earth…the Temple Mount.
