In the film, Holland visited the site of the 2015 Bataclan theatre massacre in Paris, interviewed a Salafi jihadist leader in Jordan, and then went to the Iraqi city of Sinjar, which had historically been largely populated by the Yazidi minority. In 2014, ISIS forces swept into the city and killed most of the Yazidi men and old women, taking the young women as sex slaves and the young boys to train as ISIS soldiers. At one point, Holland was shown approaching a pit filled with the remains of Yazidi women whom Isis considered too old to be used as sex slaves, and then had to vomit off-camera.
