The movie takes off with a couple of cops heading towards a lavish bungalow in Pollachi, which is shown as a haunted entity. Cut to the scene and we navigate to Chennai where the supposed protagonist, Yamuna (Nayanthara) is shown. She is caught in between a misogynist NRI who is set as an alliance by her parents and a typical boss who is focused more on professional terms than on personal/emotional concerns.

Yamuna finally decides to take a break and stay put in her grandmother's palatial house in Pollachi, which is the haunted bungalow. The house is inundated with a visually-impaired grandmother, a caretaker called Mani (Yogi Babu), lots of DTS effects such as melodramatic rocking chairs and squeaky doors, which is typically seen in any horror movie. Despite many alarms in the house assuring the existence of some spirit, Yamuna is undeterred and takes it as a joke.

Parallel to the story, the movie introduces Amudhavan (Kalaiyarasan), who is shown to have lost his beloved soul, Bhavani (Nayanthara again) in a certain road tragedy. He realizes that there are quite a number of unfortunate and distinct deaths happening around him and he feels that these deaths could be connected to that of Bhavani's.

At a certain point, both Amudhavan and Yamuna's stories get connected in the movie and how they intersect forms the rest of the plot.
