Nagesh alias Naga is an honest yet financially strained real estate broker who shares a small home with his mother and siblings, including Lakshmi, his deaf and mute sister Athulya Ravi. Naga falls for Himaja and the couple’s budding romance adds a gentle heartbeat to his challenging life.
To fund Lakshmi’s wedding, Naga must sell his ancestral property, a dilapidated movie theater. He and his close friend Kaala travel to a neighboring town to strike a deal, but a minor accommodation snag forces them to spend the night inside the theater itself, turning the place into a tense temporary home.
What begins as a business trip soon spirals into a string of inexplicable events. The theater seems haunted as strange noises, cold sensations, and eerie occurrences plague their stay. Every failed attempt to land a buyer only increases the pressure on Naga and Kaala, and the atmosphere grows increasingly oppressive.
As days pass, Naga starts having vivid dreams in which random people are murdered. When he wakes, he discovers that those very people have died in real life, one after another. He searches for answers from various godmen, hoping for a rational explanation, but nothing seems to help.
A local politician notices the pattern and suspects that something supernatural is at work. He seeks the counsel of a Nambudiri, and together they uncover a malevolent spirit haunting the theater. An exorcism is planned, yet the spirit keeps pulling Naga toward a well inside the premises. Himaja [Ashna Zaveri] reveals she has seen a vision of a murder during a video chat with Naga; though she couldn’t confirm it at the moment, Naga replays the recording and realizes that the executioner in the footage is himself, hinting that his own actions and dreams are tied to a hidden truth.
The story expands beyond a haunted theater to reveal the layered lives around Naga. Tamilselvi [Masoom Shankar], a blunt social activist known for her forthright Facebook posts, crosses paths with Dr. Sakuntala [Latha Sethupathi], who runs a small orphanage and offers free medical care to underprivileged children. The two women have plans to move some of the kids to a larger orphanage for better futures. They entrust a teenage girl to this arrangement, but soon learn that she and many other children have been taken hostage in a secluded bungalow.
Tamilselvi documents these alleged wrongs and tries to rescue the kids with Naga’s help. She uncovers a chilling conspiracy: a politician colludes with a foreign company to harvest blood plasma, exploiting vulnerable children from orphanages to supply the cosmetic industry. A police officer in the politician’s orbit brutalizes one survivor, drains her blood, and she is killed. Tamilselvi records the atrocity and, while trying to escape with Naga, is captured and attacked in the abandoned theater, ultimately being left to die in a perilous well.
The evidences Tamilselvi gathered are erased, and Dr. Sakuntala is killed in the turmoil. Tamilselvi’s spirit, long waiting for vengeance, uses the blood connection through Naga to possess him when he returns to the theater. In a shocking turn, it’s revealed that Naga’s brother Abhilash is part of the politician’s team as a doctor who draws the blood. A fierce struggle unfolds during an exorcism, and Tamilselvi’s spirit possesses Abhilash, driving him to kill the politician—and then himself. With the truth laid bare and vengeance served, Tamilselvi’s spirit departs, and Naga’s family is finally able to live in peace, free from the terror that once haunted their home and the theater.
