Jinx Holliday is a firecracker and a firestarter. Destruction always follows in her wake. And sometimes weirdos stop her and talk about her "destiny." It's all combined to create quite the aura of mystery around a 14-year-old girl who just wants some pizza rolls, and while her soul might belong to Satan, her heart belongs to the electric guitar. But one day, when Archie and company come looking for her help because Jughead is acting weird, Jinx and her BFF Danni embark on a mission to exorcize Jughead. It's the two BFFs vs. Satan for the good of humanity—or at very least, for Jinx to just be free to be a normal 14-year-old girl who just happens to dabble in necromancy and rock 'n' roll.
