The film stars Aari Arujunan, Ashna Zaveri and Masoom Shankar, while Latha, Sithara, Kaali Venkat, Abhilash, and Athulya Ravi play important roles.

Nagesh alias Naga is an honest yet unsuccessful real estate broker who lives with his mother, younger brother, and sister, Lakshmi, who is deaf and mute.

Things go fine for Naga and his family until there comes a situation where he has to sell his ancestral property - a dilapidated movie theater - to conduct Lakshmi's wedding.

Over the next few days of their stay, both Naga and Kaala experience several paranormal activities around them, and all their attempts to bring prospective buyers go futile.

He finds that there is something abnormal about all these murders and consults with a Nambudiri, who tells that a malevolent spirit from the theater is causing all this mayhem and that they have to perform an exorcism.

Naga is oblivious to all the danger that she might be in and just drops her home, but she is captured and attacked by the politician's henchmen at the abandoned theater and is thrown into the well when she is still alive and is left there to die.

Tamilselvi's spirit has been waiting for revenge since then, and when she realizes that Naga is back in the theater, she makes use of his tiny paper cut wound to possess him through blood contact, and that is how she had murdered all those men who helped the politician.
