Plot
The movie opens with the psycho beheading a woman. Gautham (Udhayanidhi Stalin), a blind musician, is in love with a radio jockey, Dahini (Aditi Rao Hydari). After multiple attempts by Gautham, Dahini finally understands his true love and asks him to meet her at a place she will be talking about in her radio session. Gautham listens to the radio all day and manages to find the place which is a train subway. Dahini hopefully waiting for him, sees the psycho-killer all of a sudden. She feels afraid and tries to escape but he manages to sedate her. 

Gautham reaches the place in time but fails to save her due to his blindness. However, using his sense of smell, he realises that something is wrong. The psycho later spares Gautham's life and takes Dahini to his secret lair. The next day, the police go to Gautham and extract information from him. A total of 14 girls were abducted, 13 of whom got murdered, and the recently kidnapped Dahini. Gautham soon realises that the police cannot find anything and he decides to seek out and save Dahini, on his own terms. The psycho is about to behead Dahini but he notices that there is no sense of fear in her. He asks her for the reason to which she replies that, Gautham will find her within a week, regardless of her death and that the psychopath will be answering for his crimes soon. The psycho leaves her chained to a wall and accepts that as a challenge. Gautham uses various methods to find the killer with the help of Kamala (Nithya Menen) a handicapped ex-police officer, who was previously dealing with the case. Together, they both deduce that the psycho must be a rich man who owns pig farms using the smell from the decayed bodies of the murdered girls. Realising that Gautham is getting closer to him, the psycho goes on a killing spree. Gautham, Kamala and their associates all visit and enquire the owners of pig farms in the area, but they have failed in their attempts. Depressed, Gautham goes to his house and stays there alone. The psycho visits him and Gautham acknowledges his presence. However, Gautham's friend, Raganayakam defends him and tries to chase down the psycho in his car. 

Unfortuntely, the psycho hides himself in a dense area of tall grass and finally manages to kill Raganayakam. The next day, Gautham mourns over the death of his friend and plans to drop his plan due to a large number of people's death. Later, Kamala reveals that she had prior notice that the killer had gone to a school function. With regained hope, they all go back to the school and look at the recordings during that day. They manage to find someone suspicious but his face got blurred. However, they notice a school staff sitting beside him. 

Using relevant information from him, they manage to find the killer. In the meantime, Dahini manages to go around the psycho's lair and sees a jailed woman and a dead police corpse.
