Prakash, a newly appointed DSP trainee, is assigned to work with SP Loganathan by ADGP Mahendran. They set out from Chennai with Veena to investigate a brutal murder in Tiruchirappalli. The assignment marks the start of a tense partnership and a high-stakes investigation.

From Chennai they travel to Tiruchirappalli to examine the murder scene in deep woods. The doctor notes the victim was strangled from the front with an iron wire, tied hair, and a neck hematoma indicating pressure points used to render unconsciousness. The brutality and mystery prompt Loganathan to anticipate more murders.

As more young women are killed in the same manner with no obvious connection, the investigators realize they are looking at copycat serial killings. The bodies are left in woods, and the victims are all in their early to mid-20s. Loganathan deduces that the killer exploits random targets to project a sense of control.

Prakash searches for historical patterns at the district library while Loganathan disguises to visit Inspector John Sebastian's house, learning that an earlier inspector had investigated similar murders in the 1970s. He discovers that John Sebastian is dead and that his son Kennedy may hold crucial clues. The case intensifies as the past and present crimes appear linked.

Prakash identifies Kennedy as the name on a reader list for Vital Points, linking the killer to the 1970s cases. The detectives tour Kennedy’s surroundings to gather more evidence but find nothing conclusive yet. The suspicion grows that Kennedy could be the killer, even as inconsistencies linger.

To get close, the team rents a nearby house to observe Kennedy without tipping him off. They fail to find decisive evidence tying Kennedy to the recent murders, keeping the case unresolved. Meanwhile an unrelated suspect is arrested by rival police and then confesses, only to commit suicide the next day.

One night, Kennedy invites Prakash to dinner at his home, hinting at a confrontation. While Prakash snoops in a dark room, he finds a photograph of a victim hidden behind a framed photo, a clue linking past victims to Kennedy. Before he can act, Kennedy knocks Prakash with a pressure-point strike and Loganathan arrives to rescue him.

Loganathan confronts Kennedy and holds him at gunpoint; Kennedy confesses to a 1970s murder he committed as a teenager and explains his abusive upbringing by his pedantic father. He reveals that his motive was to control his environment and avoid further abuse by repeating murders. He claims he stopped killing after his father's death, but the recent MO makes them doubt him.

Prakash recalls an unknown assailant who had attacked Kennedy months earlier, forcing him to reveal his knowledge of pressure points. The assailant's car had a distinctive reverse-gear alarm reminiscent of a toy rifle, a clue that later helps identify the real killer. The detectives shift focus away from Kennedy.

Following the alarm clue, the investigators trace the evidence to Muthu Selvan, a large man who fixes the past grievances with his wife. They uncover his habit of targeting women with dimples, and that Veena also has a dimple, making her the next target. The team deduces the killer’s pattern and starts pursuing him.

Muthu Selvan lures Veena to the hotel under the pretense of medicine from his car. Prakash warns her via a phone call and the two race to rescue her. A flock of disturbed birds signals danger, sending the chase into the streets.

In a tense confrontation, Muthu stabs Loganathan from behind and attempts to shoot Prakash, but a weapon misfire forces him into a vulnerable position. Prakash shoots him in the eye, ending the killer's threat. Veena is saved and the case moves toward resolution.

The team returns to their routine; Prakash gifts a music player to a neighborhood boy whose parents fight, a reflection on how responsible behavior shapes a safer future for children. Loganathan witnesses the emotional moment and praises Prakash's approach. The film closes on a note of cautious optimism.
