Justice T. Vasudev, Babu Namboothiri, is found murdered in his own house, and the killer stuffs coir into the judge's mouth. The scene unsettles the community and kicks off a tense investigation that seems to repeat a grim pattern. Days after the tragedy, Kuwait Mani, M G Soman, a close friend and businessman, appears overwhelmed with grief, but soon after he dies in what looks like an intentional car accident, with coir again discovered lodged in the victim’s mouth. The string of bizarre murders carries the same macabre signature, and Haridas Damodaran IPS, Mammootty, is assigned to lead the inquiry. He sends his trusted subordinate Joy, Lalu Alex, to pull together histories of similar killings, hoping to spot a pattern across time and space. What they uncover is chilling: Rosario Fernandes, Devan, had poisoned himself years earlier and left coir in his mouth as well. The investigators realize the victims share a college past, transforming a series of isolated incidents into a connected, almost personal vendetta. With the stakes rising, the next target appears to be the businessman Philip Thennalackal George, portrayed by Murali, intensifying the urgency of stopping the killer before more lives are claimed. The case broadens as Haridas and Joy trace another thread—Christy, the son of Rosario Fernandes and Sreedevi Rosario, emerges as a central figure in the growing web of clues. Suresh Gopi brings Christy to the foreground as a person of interest in the unfolding tragedy.
To piece the full picture, Haridas books time with Sreedevi’s family and medical background. Sreedevi Rosario, played by Lakshmi, had died bedridden from illness long before, and this history adds layers to the mystery. Haridas’s pursuit of truth leads him to Sreedevi’s father, C. K. Gopala Menon, while nurses and aides shed more light on Christy’s presence at key moments. Nurse Leeladevi, Kaviyoor Ponnamma, confirms that Christy was present in the hospital around Sreedevi’s death, cementing his involvement in the tangled past. Meanwhile, Philip’s testimony exposes a painful chapter from their college days: all four men—Vasudev, Mani, Rosario, and Christy’s father—harbored deep, unreciprocated feelings for Sreedevi, and a grave wrong was committed when they assaulted her during those years. The sense of shared guilt begins to map out the motive behind the killings, fueling Haridas’s resolve to uncover the mastermind behind the chain.
As the investigation widens, Haridas attends a high-profile event where Warrier, a legendary spiritual leader with a worldwide following, appears as the chief guest. Warrier, portrayed by Nedumudi Venu, is a figure who radiates influence and mystery. Later, Warrier allegedly locks someone inside his house and summons Haridas for help, claiming that a stranger intended to kill him; the ensuing encounter leaves the killer on the loose and deepens the intrigue surrounding Warrier’s past and motives. The investigation tightens its focus as Christy is arrested on murder charges and returned to the mental asylum for treatment, a development that tests Haridas’s job security and authority.
During treatment, Christy is subjected to Narcosynthesis, a process meant to reveal the truth under controlled conditions. The technique suggests that Christy has been manipulated by a powerful, unseen hand, and his subsequent behavior raises the stakes for the case’s final chapters. Christy manages a dramatic escape from the hospital, a move that directly threatens Haridas’s standing and compels him to act with renewed urgency. Philip’s safety becomes a pressing concern, but Haridas declines to offer protection, a decision that heightens the tension as the clock ticks toward a conclusion. Together, Haridas and Joy keep watch on Philip’s residence, hoping to expose the unseen conspirator.
The trail leads unavoidably toward Warrier, whose past actions and volatile psychology align with the motive behind the series of killings. The truth of Sreedevi’s past and the various acts of violence committed by the college circle converge to reveal Warrier as the architect of the vendetta, driven by perceived injustice and a long-standing grievance. With the case closing in, Christy is declared innocent and reintegrated into a normal life, while Warrier is eventually arrested for the serial killings, his elaborate plan exposed and dismantled. In the aftermath, the film leaves viewers with a somber meditation on memory, revenge, and the fragile line between righteousness and vengeance. The investigation, the confessions, and the eventual downfall weave a dark tapestry that underscores how past wounds can echo through time, shaping a present where justice seeks to correct what was once wrong.
