ABBY

Dr. Garrett Williams explains to his students, "Eshu is the most powerful of all earthly deities. Eshu is a trickster, creator of whirlwinds... chaos."

While on an archaeological dig in a cave in Nigeria, Dr. Williams finds a small puzzle box, carved with the symbols of Eshu: the whirlwind, the cock's comb, and the erect phallus. When Dr. Williams discovers the mechanism to open the box and unlatches it, a tremendous wind blasts out, knocking Dr. Williams and his men against the cave walls and floor.

The spirit released by Dr. Williams travels to Louisville, Kentucky. Dr. Williams' son, Emmett, and Emmett's wife, Abby, are moving into a new house, and that night, strange events happen in the house, including Abby becoming possessed. The signs start small, with Abby getting aroused in the shower, but slowly get more bizarre and dangerous, with her lashing out at people or trying to seduce various men.

Emmett takes Abby to the hospital, where the doctors note no neurological abnormalities, but recommend she see a psychiatrist. When Emmett gets home, he calls Dr Williams back home, telling him her situation has worsened. As Dr Williams lands back in Louisville, Abby escapes the hospital, and when she gets back home, tries to seduce Dr Williams. When he rejects her advances and reprimands the demon inside her, she uses her demonic powers to shake the house. While the men struggle to get back on their feet, Abby escapes, and Emmett steals a car to try and find her. Abby's brother Cass arrives to help, and Dr Williams tells him about Eshu and if Abby is not exorcised, the demon will kill her.

Abby escapes to a nightclub and seduces various men until Emmett and Cass arrive and try to stop her. When all else fails, Dr Williams arrives at the club, and he, Emmett, and Cass manage to exorcise the demon (to which Dr Williams confirms to be a fake Eshu) out of Abby. The spirit returns to the box in which it came, and Emmett comforts a crying Abby, who is unaware of what has happened. Emmett and Abby then go on a vacation, still a happy couple.

The demon is exorcised from Abby with the help of Dr. Williams, Emmett, and Cass, returning the spirit to the box. Abby, unaware of her ordeal, is comforted by Emmett and they go on vacation together.

Abby's ending restores the status quo after a supernatural ordeal, emphasizing the resilience of family and the effectiveness of traditional exorcism rituals. The film closes on a note of recovery and unity, while hinting that the origins of evil can be both ancient and alarmingly close to home.
