It starts with Sookie going to the fairy world, where she meets her grandfather. Her grandfather tells her that she has only been there for two days, but two days in the fairy world is equivalent to twenty years in the human world. It has been a year since Sookie left the fairy world and returned to the human world. Sam happily chats with a group of shapeshifter friends, and Tara leaves town. At this time, Bill is already the new king of Louisiana. Eric is under him. It turns out that Bill was a spy sent by the authorities to the original Queen. At this time, Jessica is also with her lover Hoyt. Lafayette and his gay boyfriend start to attend some wizard gatherings. The gathering is held by an old woman Marnie who loves magic (the villain of this season). Marnie summons the ghost of Antoneo, a female witch who massacred vampires hundreds of years ago but was burned to death. Bill knows that there is a witch gathering and sends Eric to investigate. As a result, Marnie, who is possessed by Antoneo, loses his memory under the spell cast by Marnie. Sookie, who is driving home, finds Eric with amnesia and takes him home. Without the burden of a thousand-year memory and his contempt for humans and self-protection, Eric shows his pure and straightforward nature. Sookie loves and fears the arrogant thousand-year-old vampire in the past, but she cannot resist this amnesiac version of Eric and gradually lets down her guard. Even though the spirit of her dead grandmother warns her that this state is only temporary, she still can't help falling in love with Eric. Jason was kidnapped by the leopard man's girlfriend and sexually assaulted. Although he escaped later, he was seriously injured and was saved by Jessica and Hoyt who passed by. At the same time, he gradually fell in love with Jessica because of Jessica's blood. Later, Eric and Sookie assisted Bill in fighting Marnie and her wizard minions. In the chaos, Sookie was hit by a stray bullet, and Eric was controlled by Marnie. The seriously injured Sookie was rescued by Alcide and Bill. Bill gave his blood to Sookie and saved her life. However, Sookie, who had the blood of two vampires in her body, fell into an emotional dilemma. In the 10th episode of the season, Sookie's spirit power helped Eric recover his memory, and he also found out that Marnie was the mastermind behind the scenes, and Antoneo was just a puppet controlled by her. At the same time, Lafayette was also found to be a medium who could see ghosts. Sookie and others were trapped in the Luna Hotel, which was used for gatherings. At the same time, Andy "fell in love" with a spirit. In the end, because Sookie's power broke out again, Marnie's spell failed again, and Bill and Eric were able to enter the hotel and shoot Marnie. But Marnie's ghost was still there, and possessed Lafayette when she fell asleep.
