In a massive street protest by lawyers across the city, Abdullah, in an altered appearance, kidnaps Judge Vedhachalam after introducing himself as 'Citizen'.

The CBI team tracks down a former employee of the local government, which Attipatti was under, and visits Father Louis at Lutheran Chapel.

Sarojini and her team find hundreds of dead bodies buried near the coastal area where the location of Attipatti was, and a tombstone bearing the names of all who perished.

Sarojini concludes that Arivanandam and Anthony, the name of a boy baptised after the atrocity, are the same people, and her further investigation leads her to Abdullah, who manages to escape via a secret route.

The villagers later found out that the district collector, the MLA, the DGP, and the judge had taken 150 million rupees allocated by the government to build the wall.

One night, they arrived at Attipatti with henchmen, caught all the villagers, tied them on a boat, tortured them, and pushed them to the sea, killing all except Arivanandam.

With the judge, DGP, and district collector on the witness stand, Citizen tells the court that the death penalty or life imprisonment is lenient for them.
