They manage to find someone suspicious, but his face got blurred. With regained hope, they all go back to the college and look at the recordings during that day. Later, Kamala reveals that she had prior notice that the killer had gone to a college function.

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 deaths. Unfortunately, the psycho hides himself in a dense area of tall grass and finally manages to kill Rajanayakam.

However, Gautham's friend Rajanayakam defends him and tries to chase down the psycho in his car. The psycho visits him, and Gautham acknowledges his presence. Depressed, Gautham goes to his house and stays there alone. Gautham, Kamala, and their associates all visit and enquire the owners of pig farms in the area, but they have failed in their attempts. Realizing that Gautham is getting closer to him, the psycho goes on a killing spree. 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. Gautham uses various methods to find the killer with the help of Kamala, a handicapped ex-police officer who was previously dealing with the case. The psycho leaves her chained to a wall and accepts that as a challenge. 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 psycho will be answering for his crimes soon. The psycho is about to behead Dagini, but he notices that there is no sense of fear in her. Gautham soon realizes that the police cannot find anything, and he decides to seek out and save Dagini on his own terms. A total of 14 girls were abducted, 13 of whom got murdered, and the recently kidnapped Dagini. The next day, the police goes go to Gautham and extract information from him. However, using his sense of smell, he realizes that something is wrong. Gautham reaches the place in time but fails to save her due to his blindness.

She feels afraid and tries to escape, but the psycho manages to sedate her. Daginii, hopefully waiting for him, sees the psycho-killer all of a sudden. Gautham listens to the radio all day and manages to find the place, which is a train station. After multiple attempts by Gautham, Dagini asks him to meet her at a place that she will be talking about in her radio session. Gautham, a blind musician, is in love with a radio jockey named Dagini. The movie opens with the psycho beheading a woman.
