Sookie takes him home - he doesn't realize that he owns the house - and contacts Pam for help. Tara is concerned when Lafayette disappears. Jason is still being held prisoner by Crystal and her backwoods clan and learns exactly what they have in store for him. Sam Merlotte takes his brother Tommy to task for wanting to cheat Mrs. Fortenberry out of a possible fortune. Jessica seeks Bill's advice after feeding on a pick-up at Fangtasia. Sookie gets a surprise visit from the faerie world.

She gets more than she bargained for. Bill gets to meet Portia Bellefleur's mother but learns something about her that brings their relationship to an abrupt end. Jason manages to escape from Crystal and her clan and is eventually rescued by familiar faces. Terry and Arlene's baby has a message for him. After his falling out with Sam, Tommy finds his mother but isn't quite expecting the kind of welcome he gets.

With Pam's body now rotting as the result of the witch's spell, Bill decides to take action and imprisons Marnie, who continues to have visions of an ancient spirit. He wants her to reverse the spell she's placed on Pam but she says she simply doesn't know how. Bill is none too pleased when he learns that Sookie is hiding Eric. Neither is Tara who refuses to believe that Eric has changed. Meanwhile, Jason is recovering and has an erotic dream involving Jessica. He also learns that a full moon is in the offing. Arlene and Terry decide they need an exorcism and seek some local help. Lafayette and Jesus head to Mexico to get some help of their own.

Bill is livid when he hears that Sookie has been hiding Eric in her house. He arrests him and puts him in the same cell with Pam, who is still rotting away. He also asks the Authority to put Eric to the true death. Marnie is also in Bill's prison but connects with the spirit of the witch from the past who had a deadly spell for dealing with vampires. It's also a full moon and Jason fully expects to turn into a were-panther. Sookie sits up with him but when he runs off into the woods, it's Jessica who comforts him. With Sam away taking care of Arlene's burnt out house, Tommy shifts into something he has never experienced before. In Mexico. Lafayette and Jesus seek help.

As all hell breaks loose in Shreveport, Sookie summons her most potent powers yet to save Bill, in the process breaking a spell and leading Marnie/Antonia to re-evaluate her mission. Jason urges Jessica to glamour him for Hoyt's sake; Terry drags Andy to "Fort Bellefleur" for an intervention; Alcide reconsiders his allegiances after Marcus fight with Tommy; Jesus, accompanied by Sookie, Lafayette and Jason, tries to breach the Moongoddess Emporium's defenses to liberate Tara and Holly, while Bill leads a brigade of vampires committed to blowing the place to kingdom come.

Bill, Eric, Pam and Jessica descend on the witch's coven, intent on killing Marnie and anyone else who poses a threat to them. They're not quite prepared for the barrier Marnie has set up around the emporium and realize they may have a bigger fight on their hands than they had anticipated. Inside the emporium, Marnie is having her own problems with Antonia, who is no longer as keen as her host to destroy the vampires. Even after the vampires find a way in, it appears that Marnie will not be easily disposed of. Sam and Alcide track down Marcus who has kidnapped his own daughter. Sam wants to end any threat to Luna and her daughter. Andy Bellefleur meanwhile has an interesting encounter in the woods.

Now free, Sookie must decide between Eric and Bill. It's not an easy decision and she soon realizes that her turmoils are not yet over when someone comes gunning for her. Having taken over Lafayette's body, Marnie is intent on seeking revenge. She also wants additional powers however and knows exactly where to get them. Sookie has to save Bill and Eric from her but gets help from an unexpected source. Jason meanwhile decides it's time to tell Hoyt about sleeping with Jessica. Hoyt doesn't take it too well. Jason and Jessica however come to an understanding about their relationship.
