To free themselves from the attic and stop the epic war at the amusement park, the Krewe must convince Nelson that his dad's beliefs are wrong; Soleil must make a choice between good and evil, but her decision racks her with guilt.
After learning from Honey Lou the Swamp Monster that the Feu Follet trapped the soul of Pat's dad at the Court of Light, the Krewe helps Pat say one last goodbye.
The Krewe has an opportunity to sneak into Furst Mansion and find proof that Furst is the one working with Belial; their cover is almost blown when it turns out Furst is hosting a meeting with the rougarous and vampires.
When the Krewe goes on a field trip to the swamp, they find out Pat used to live there until his dad passed away in a gator accident; Pat never believed the story, and a mysterious voice offers to tell him the truth.
The Krewe gets caught, just as Furst and Belial planned; after facing Belial for the first time, Soleil experiences true horror and her spirit is broken.
Soleil and Stanley learn there's more to each other as they desperately try to save his little sister Cece from rougarou Missy; Pat and Maybe search for offerings to summon Ogoun.
With the girls doing their own thing, Stanley plans a bro-day to include Nelson with the guys from the Krewe. Everyone tries to make it work but they just seem to be from different worlds until one of Belial's demons threatens Stanley.
The Krewe takes a trip to the underworld in order to defeat the rot demon and save Missy. While there, Soleil discovers she still has the dark flames, and they're the only powers that work in the underworld.
