Simon and his friends return a life-sized cutout of Vijay to a local theater. Indran's car hits the cutout, breaking its legs. In a fit of rage, the boys confront Indran and his gang, sparking a street brawl.

Indran is admitted to the hospital after the fight. Simon is arrested by SI Satyan on suspicions related to the melee. CI Alex, who has ties to Simon and his friends, intervenes and secures Simon's release.

While examining a fully burnt body, Yesudas the constable recovers a flash drive. Goons from Arjunan's gang arrive to retrieve the drive, but Simon fights them off. Yesudas returns the drive to Arjunan and pleads for his son's safety.

To contact Deepa, Simon takes Ganesh's daughter Jennifer to Deepa's dance class. After the class, Simon drops Jenni at her home. This arrangement is meant to help Deepa hear from Simon about Vijay-related matters.

Ganesh informs Simon that Jenni is missing. Simon launches a town-wide search to find her. His investigation uncovers a racket that abducts children for begging.

Jenni is released by the gang and taken to the hospital. Relatives rush to the hospital for her safety. Simon realises the gang is involved in the child racket.

Simon learns that Arjunan is behind the racket and that some children are being used in organ trade. He begins gathering evidence and links the case to Arjunan's hospital activities. The gravity of the operation becomes clear.

It is revealed that the burnt body is Doctor Jomon, who had uncovered the illegal activities in Arjunan's hospital and placed those details on the flash drive. The culprits burned his body to erase the evidence. The flash drive becomes crucial evidence linking Arjunan to the racket.

Biju had taken a copy of the flash drive's contents hoping for an adult film. The drive instead contains detailed information about Arjunan's racket. This accidental discovery alerts the group to the depth of the crime.

Simon and his friends, with CI Alex and Professor Seetharaman, confront Arjunan and his gang at their hideout. It is revealed that Alex was Arjunan's partner in crime, aiming to win local support for an election. He had wooed Thalapathy fans to bolster the gang's power.

The beggar gang member tells Simon about Alex's involvement. A clash erupts between Thalapathy fan supporters and Arjunan's gang, as the truth begins to surface and tensions rise.

Alex and Arjunan, along with their gang, are taken into custody and sent to jail. The arrest marks a turning point in the battle against the criminal operation.

In prison, Alex explains to his inmates how he ended up in jail, detailing his schemes to manipulate local politics for personal gain. He reveals how the alliance with Arjunan started and why it collapsed.

Simon has become a police constable, continuing to fight crime. In the final scene, he and Deepa watch a Vijay movie, Bairavaa, on screen, celebrating their bond and the justice achieved.
