She wasn't dead...

A stormy night in Kerala, a large tree branch falls and breaks the roof of an outhouse. The woman inspecting the outhouse ends up in a hospital.

In another town, the woman’s daughter, Amy, and her husband, Ben, argue about not being able to celebrate her birthday together. Amy gets a call about her mother’s accident and they quickly fly to Kerala.

In Kerala, Amy begins having visions that make her believe her dead conjoined twin’s soul is after her. Her husband does not believe her and sends her to his former professor for spiritual healing.

During the treatment period, she tells the professor about how her conjoined twin sister Cindy always hated that Ben liked Amy more than her. In fact, it was when Ben told Amy that he was coming back home from abroad that Amy decided to separate from Cindy. It was during this operation that Cindy died, and Amy blames herself for her sister’s death. The professor reassures Amy that her visions of Cindy are the result of her guilt and only a figment of her subconscious mind.

At her mother’s place that night, Amy is forced into the outhouse by an unseen entity. Hearing noises, Ben wakes up and finds her unconscious in the outhouse. When Amy awakes, she is possessed by Cindy’s soul. After this, Amy and Cindy can’t get enough of Ben. When the professor meets her again, he feels there is something wrong and tells Ben to keep an eye on her, which she overhears.

The caretaker suggests that a ritual is performed on Amy and Cindy. After the ritual, Cindy’s stronghold on Amy escalates and her true colors are shown, resulting in an exorcist being called in.

During the kanjar, Cindy reveals that she was murdered. As she leaves Amy’s body, she urges Ben to discover the truth of her death. After Amy wakes up, Ben threatens to leave her. Amy tells him that years ago when he called her to tell Cindy that he was coming home, Cindy lost her mind and tried to kill her because she had feelings for Ben too. In self-defense, Amy hit Cindy on the head with a glass music box, killing her. Their mother covered the truth to protect her daughter. After consulting with the professor, they try to find and burn the last possession of Cindy and set her soul free.

Amy, Ben, the caretaker, and her daughter-in-law all follow the music leading to the outhouse. Under the floor, they find Cindy’s corpse. The caretaker and her daughter-in-law go inside to get kerosene with which to burn the body. They both die at the hands of Cindy’s soul. The professor arrives at the outhouse with kerosene, but is possessed by Cindy and tries to attack Amy. While Ben fights him, he finds the locket he gave to Amy when they were young on Cindy’s corpse. When he confronts Amy, she confesses that she is actually Cindy. She tells him that she killed Amy with the music box and took her sister’s place so she could be with Ben. Outraged,Ben decides to leave her despite her pleas that she loves him. Amy (now revealed to be Cindy) hits him on the head with a chair to stop him from leaving and he falls. Cindy tries to kill Amy with a pair of scissors but is stopped by Amy’s soul, the burning roof falls on Cindy thus killing her and professor saves Ben. Ben sees Amy’s soul smiling at him and then disappearing in the fire.
