Ranjith Kalidoss, a DSP in CB-CID, is paired with Inspectors Joseph and Vandana to tackle a powerful group of five criminals whose political and economic influence makes them hard to prosecute. His superiors demand a direct, hard-hitting takedown, but Ranjith argues for a riskier, more strategic approach. The assignment sets the tone for a tense, high-stakes investigation that will test the team.

A parcel lands at the police station containing a small horse doll hanging on a noose, its figure marked with four holes and no other clues. The clue is easy to overlook, yet it surfaces again as the killer’s taunts begin. The team notes the ominous clue while planning the pursuit of the five criminals.

Shivanand, a local communist leader, goes missing and is later discovered in a warehouse, hanging from the ceiling with his face covered by an animal mask. The grisly scene shows the killer’s escalating cruelty and signals a broader deadly pattern. The investigation widens to connect these murders to the earlier case files.

Ranjith receives a diagnosis of Parkinson's disease, a condition that slows his reflexes and dampens his usual efficiency. The news strains his personal happiness and threatens his professional effectiveness. The team must adapt to his changing abilities as the case grows more dangerous.

The killer continues to taunt the team by sending clues while killing Vishnu, a lawyer, and Dr. Ramya, a pathologist. Each murder sharpens the sense of danger around the investigation. Ranjith trails a clue toward the killer, but his tremors hinder progress at a critical moment.

Despite following a key lead, Ranjith's Parkinson's symptoms slow him down just as he closes in on the suspect. The killer knocks him out and escapes, leaving the team frustrated and more determined. The personal risk to Ranjith deepens the emotional stakes of the pursuit.

Back at the station, the team informs Ranjith of a dead body in one building, but Ranjith already senses and describes what they will find. He concludes that he himself is the killer’s next target, heightening the urgency of the investigation. The scene marks a turning point in his self-deduction and resolve.

Ranjith reopens a case from years earlier involving Emmanuel and his wife, a wealthy architect couple, and their missing caretaker Mariadas. He spots anomalies—like a new golf club—that tie the past to present killings. The investigation leads to a confession about Catherine and Mariadas, revealing a deadly family secret that ends in suicides.

Emmanuel and his wife confess the truth behind Catherine’s death and Mariadas’s murder, explaining Catherine’s puberty-triggered distress. In a final twist, the couple hang themselves after the confession. Dr. Ramya handles Catherine’s autopsy as the prosecutor prepares for court, confirming the gravity of the case.

The investigation points toward Emmanuel’s nephew Christopher, who has motive, means, and pharmaceutical knowledge. Immigration checks confirm his recent arrival in India, raising his profile as a potential serial killer. Meanwhile, anticipation grows as the team closes in on further connections.

A cop is dispatched to Christopher’s residence to gather evidence but is killed before he can report back, escalating the danger and complicating the case. The team realizes Christopher is a dangerous and possibly trapped target. Tension peaks as the hunt intensifies.

Ranjith leaves the hospital to confront Christopher at a warehouse. He finds Joseph and Vandana on the floor with nooses around their necks during a tense confrontation. After a long struggle, Ranjith overpowers Christopher and hangs him, transforming the warehouse into a dramatic showdown scene.

As reporters converge on the warehouse, Ranjith tells them that Christopher is another victim of the serial killer, shifting public perception. The press captures the moment, adding gravity to the revelation. The line between killer and victim becomes a central twist of the investigation.

A few days later, Joseph and Vandana confront Ranjith about why he did not inform the press that Christopher was the serial killer. He reveals his overarching plan: kill the five criminals and frame the serial killer as the culprit. The plan succeeds, presenting a chilling twist on justice and vengeance.
