Gautham, a blind musician, cherishes a deep affection for Dagini, a radio jockey who uses her airwaves to draw him in. After several attempts to connect, Dagini asks him to meet at a place she will hint at during a live radio session. He spends the day listening intently to her program and, through careful listening and intuition, traces the clue to a location—the train station. Dagini waits there, hopeful, but a sad twist arrives when the psycho-killer turns up. She tries to flee, yet he manages to sedate her. Gautham reaches the scene just in time but cannot intervene in the brutal moment because his blindness blinds him to the danger in front of him. Still, his other senses sharpen, and he detects something deeply wrong through a keen sense of smell in the air, a small but telling hint that something horrific has taken place.
The next day, a grim police briefing reveals a chilling tally: 14 girls have been abducted, 13 of whom were murdered, and the 14th—Dagini—has vanished into the killer’s hands. The revelation shakes Gautham, who realizes that the authorities seem unable to uncover the truth quickly enough. Refusing to surrender to despair, he decides to pursue the killer on his own terms. The psycho is about to execute Dagini, but she remains unnervingly calm and even defiant. When questioned about her resilience, she asserts that Gautham will find her within a week, and that the killer will have to answer for his crimes. The scene closes with Dagini still chained to a wall, the killer leaving her behind as a taunting challenge. A prostitute in the neighborhood becomes another tragic victim, abducted and killed by the same predator, underscoring the killer’s reach and the danger looming over them all.
Driven by a mix of determination and desperation, Gautham teams up with Kamala, a handicapped ex-cop who previously grappled with the case, and a network of associates who share his resolve. Their search leads them down a volatile path as they piece together fragments of evidence, trying to map out a murderer who seems to operate from wealth and influence. The investigation points toward a man who owns pig farms, a scent-based clue drawn from the decayed bodies of the murdered girls. Despite their relentless pursuit, the trail remains frustratingly cold, and a heavy blow lands when Rajanayakam, a loyal friend, is killed in the course of the chase. Grief and anger test Gautham as he wrestles with the possibility that the killer might slip away.
Kamala reveals a critical lead: there was prior notice that the killer attended a college function. Armed with this new information, the team returns to the college, scrutinizing recordings from that day. A suspect emerges, though his face is blurred in the footage; a college staff member sits beside him, offering a misleading sense of normalcy. Using a careful synthesis of details gathered from informal informants and official records, they narrow the field and identify Angulimala as the killer. Dagini, meanwhile, ventures into the killer’s lair and discovers a jailed woman and a dead police officer, deepening the sense of the killer’s reach and the brutality of his crimes. Dagini’s bravery becomes a window into the killer’s past, as she learns that Angulimala was her former student and that his violent impulses had roots in a brutal history of punishment.
As the clock nears 11:45 PM, Gautham reaches the killer’s lair. The moment of peril escalates as the intruder alarm activates and the psycho rushes to behead Dagini. In a fierce struggle, Gautham manages to cuff the killer’s leg, buying precious seconds for a escape. He and Dagini make a break for freedom, accompanied by Kamala, and the trio flees from the danger. The killer’s fury streaks after them, but the pursuit is interrupted when the killer’s imprisoned former teacher—who had subjected him to relentless punishment—grabs the key to unlock the cuffs and swallows it, a stark act of cruel punishment that only intensifies the chase. The killer overpowers the teacher in a destructive frenzy and sprints to catch up to his quarry, but the trio manages to slip away.
In the aftermath, Dagini’s perspective shifts dramatically as she is drawn into a disturbing form of Stockholm Syndrome during a subsequent press appearance. She speaks of the killer with a surprising degree of sympathy, suggesting that if she had been a mother or sister to him, she might have cared for him to spare him from his pain. The killer, watching the interview, begins to confront the consequences of his own actions after finally feeling a sliver of being understood and loved. Overcome by a paradoxical mix of remorse and relief, he steps toward a cliff with a faint smile, signaling a grim sense of closure that leaves the audience unsettled and reflective about the power of affection, fear, and the lines between victim, perpetrator, and the human need for connection.
