Dhanasekaran lives off-grid at a secluded farmhouse with Murugan and Subu. He is an ex-policeman haunted by a traumatic past and possesses a mind-reading ability that his ex-boss Raghuram uses to solve cases unofficially. He hallucinates his lover Stella, which adds to his instability.

Raghuram assigns Naushad to Dhana for interrogation in a rape-and-murder case. Naushad's mind-reading seems unaffected under the intense questioning, hinting at innocence or secrecy. The case triggers Dhana's uneasy cooperation with his former boss.

During the third-degree interrogation, Naushad escapes custody when the police sent by Raghuram return to take him back. Raghuram, fearing job loss, imposes a 24-hour deadline to bring Naushad back. The deadline heightens the pressure on Dhana to act quickly.

Dhana leaves the farmhouse after thirteen years to track Naushad to the city and ensure his custody. On the road, he begins recalling Stella and their life together, hinting at the reason for his isolation. The journey marks a turning point from passive support to active pursuit.

In a flashback, Stella is raped and murdered by her cousin Robert after she rejects him. Dhana's inability to protect Stella contributes to his seclusion at the farmhouse with Murugan and Subu. The memory intensifies his resolve as he travels back.

Instead of pursuing Naushad, Dhana tracks Abhishek, the spoiled son of a lawyer, and abducts him to the farmhouse for interrogation. He uses his mind-reading to probe Abhishek's guilt and uncover the truth surrounding the girl's murder. The plan shifts the focus from Naushad to a different suspect.

Dhana discovers Abhishek is the real killer of the girl who loved Naushad and that Naushad was framed. He locks Abhishek in an underground cell within the farmhouse. This revelation redefines the case and escalates the tension inside the compound.

Robert, Stella's cousin, is also imprisoned in the underground cell for thirteen years. He describes the inhuman torture Dhana inflicted daily and urges Abhishek to confess and go to prison to escape that fate. The underground cell becomes a crucible for truth and punishment.

Abhishek decides to confess and does so on camera, which leads to a court conviction for a life sentence. The confession seems to seal the case, yet the truth is entangled with Dhana's coercive methods. The verdict triggers a chain of consequences beyond the courtroom.

After the court, Abhishek's father confronts the beating and learns that Dhana orchestrated it by bribing a member of Raghuram's team. He mobilizes a group of thugs to finish Dhana at the farmhouse. The plan foreshadows a deadly confrontation and Dhana's collapsing world.

That night, the assailants join with local goons previously beaten by Dhana to assault him. He fights back but is gravely injured, refusing to seek medical help. The farmhouse becomes a battlefield that echoes Stella's earlier tragedy.

Dhana dies in the farmhouse, unable to receive treatment, which mirrors Stella's death thirteen years earlier. A second hearing later rules that the earlier videotape against Abhishek was coerced, and he is acquitted due to lack of evidence. The justice system's flip-flop contrasts with Dhana's personal vendetta.

The lawyer-father is killed by Raghuram, who makes it look like an accident. Abhishek ends up as the new inmate in the underground cell along with Robert. The film pivots to a grim tableau of punishment continuing beyond one life.

The film closes with a group photo of the farmhouse's new members—Dhana, Murugan, Subu, Naushad, and Stella (visible to Naushad and Subu). Robert and Abhishek remain imprisoned in the underground cell. The image suggests a haunting continuity of the past within the farmhouse.
