[1] Two years after the events in 4 the People, Rajan Mathew (Narain) is working an administrative job after being transferred for killing Vivek among the four-member group, and the remaining three members- Arvind Sebastian (Arun), Eshwar (Arjun Bose) and Shafeek (Padma Kumar) are imprisoned.

Angered by the suicide of a student who is mocked and refused a loan for her studies, they eventually kill the corrupt bank manager who abetted it.

The team learn about Rajan's reinstatement, and decide to kidnap him, building trust with his wife through their ally Kamini (Surabhi Lakshmi).

Rajan's investigation leads to a powerful kingmaker and minister Paramasivam (Vincent Asokan) who controls the media and political parties.

The first victim is inspector Thomas, Rajan's corrupt superior, who is killed when a roller coaster he inaugurates goes off track, which was rigged by the team.

Rajan then hurriedly releases the incarcerated '4 the people team', who arrive incognito at the venue and assassinate Paramasivam point blank and break away.
