Psycho - The Killer

The story opens with the psycho beheading a woman.

Kishore, a blind musician, is in love with a radio jockey named Delphi. After multiple attempts by Kishore, Delphi asks him to meet her at a place she will talk about in her radio session. Kishore listens to the radio all day and manages to find the place, which is a train station. Delphi, hopefully waiting for him, sees the psycho-killer all of a sudden. She feels afraid and tries to escape, but the psycho manages to kidnap her.

Kishore reaches the place in time but fails to save her due to his blindness. However, using his sense of smell, he realizes that something is wrong. The next day, the police go to Kishore and extract information from him. A total of 20 girls were abducted, 16 of whom got murdered, and the recently kidnapped Delphi. Kishore soon realizes that the police cannot find anything, and he decides to seek out and save Delphi on his own terms. The psycho is about to behead Delphi, but he notices that there is no sense of fear in her. He asks her why, to which she replies that Kishore will find her within a week regardless of her death and that the psycho will be answering for his crimes soon. The psycho leaves her chained to a wall and accepts that as a challenge. Kishore uses various methods to find the killer with the help of Shyamala, an ex-police officer who was previously dealing with the case. Together, they both deduce that the psycho must be a rich man who owns cow farms using the smell from the decayed bodies of the murdered girls. Realizing that Kishore is getting closer to him, the psycho goes on a killing. Kishore, Shyamala, and their associates all visit and enquire about the owners of cow farms in the area, but they have failed in their attempts. Depressed Kishore goes to his house and stays there alone. The psycho visits him, and Kishore acknowledges his presence. However, Kishore's friend Subash defends him and tries to chase down the psycho in his car.

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

Using relevant information from him, they manage to find the killer. In the meantime, Delphi manages to go around the psycho's place and sees a jailed woman and a dead police corpse. She reveals to her that the psycho was her former student and the psycho used to masturbate, so she used to beat him 50 times every day, for all 365 days in a year for his mistake. Around midnight, Kishore reaches the psycho's place. The psycho is about to kill Delphi, the intruder alarms get activated. The psycho runs to kill Kishore, but eventually, Kishore manages to cuff the psycho's leg. Kishore later runs and rescues Delphi. They both manage to run away.

However, the psycho begs out, "Teacher, please don't leave me alone here". Delphi, who sees the light in him, places the keys to the cuff a few meters in front of him. Later, they both escape together with Shyamala. The psycho is about to take the key, but the imprisoned teacher takes the key and swallows it, trying to punish him. The psycho gets frustrated and tears her stomach to get the key. He later releases himself and runs to find them both. Fortunately, they both leave, and he screams as if he failed.

Later on, it is evident that Delphi has been affected by some disease, as she sympathizes with the psychopath when questioned by the press and refuses to consider him a killer but understands his innocent heart filled with pain and she were his mother or sister, she would have cared for him so that he would not have become the killer that he was. The psycho sees the interview and realizes his mistakes after finally feeling loved by someone.

The movie ends with the psycho jumping off a cliff with a smile on his face.
