Kay reluctantly joins the youth group at Stone Mission Church in Orange County California, but she's shocked when she walks in on her youth group leaders, Meg and Cortland, in the middle of a read-life exorcism. They reveal that they are a part of a secret organization of demon hunters in a war that's heating up, and Kay soon discovers she's a "Blight," a human who demons can't possess. Kay joins Meg, Cortland, and members of other interfaith groups fighting demons in Orange County, and they soon find themselves facing an even bigger threat.
