Soleil Le Claire, a girl who lives for horror, accidentally breaks a spell on the Tree of Life and unleashes an ancient evil. The spirit of Marie Laveau, the voodoo queen of New Orleans, puts her and four other kids in charge of saving the city from Belial, an ancient demon who feeds on fear. Luckily, they're not alone, as each kid gets a special gift from the voodoo spirits called Loa. Eventually they learn their town's biggest secret: Vampires, rougarous, ghosts, monsters and demons are real and have secretly lived among humans for decades. The Krewe will have to hone their powers, figure out what Belial's up to and keep the peace between creatures as they go head-to-head with local legends from the underworld.
