[4][5] Naan Mahaan Alla was released on 20 August 2011 to positive reviews from critics with praise for the cast performances, action sequences and realistic tone.

Pragasam is brought home and Jeeva starts taking responsibility for his family by reclaiming his lost job and maintaining all the accounts.

Looking at the news reports of the girl that boarded his taxi and was raped and then mutilated by the gang, Pragasam calls Jeeva to accompany him to the morgue, where he helps the investigating officer by providing clues about the killer.

The gang then creates a stampede by throwing bottles as one of them stabs Pragasam with a piece of poisoned glass shard.

With his influence, Kutti Nadesan asks his gang to bring all the guys who plan for a murder in Chennai so that Jeeva can identify him.

While his previous work was based on sporting incidents in a rural background, this one was said to be a "total city subject", shot entirely in Chennai.
