Gopal Iyer(Satyaraj) is a Deputy Commissioner who doesn't think twice about disposing off antisocial elements through fake encounters. Coming from an orthodox Brahmin family, he has earned his peace-loving father's ire through this attitude of his. A widower, Iyer also earned his father's displeasure by marrying Nasrin(Sangavi), a Muslim and as a result, his father has not spoken to either Iyer or his son. One of the dadas Iyer has put in jail is Venkatachalapathy(Satyaraj), who attempted to create a law and order problem in the city to topple the Government. The dada is counting his days to get out of jail and extract his revenge on Iyer. Meanwhile Jennifer(Mega) threatens to unmask Iyer since she has filmed one of his fake encounters.

With the Brahmin community(with exaggerated behavior and accents) typically being used as a comedy element in Tamil movies, a Brahmin hero - and a police to boot - seemed like a concept that would deliver a different movie. And the conflicts such a police officer would face, both internally and with his orthodox family, could have delivered a movie with a strong, emotional core. But Iyer I.P.S is definitely not that movie! The movie is filled with caricatures rather than real people and none of the characters ring true. The way Satyaraj deals with criminals in staged encounters is cliched and his arguments with his father are loud but empty. The villain too seems almost like an afterthought with no background and consequently, the few meetings between the two Satyarajs lack fire too.

The director makes our jaws drop in shock more than once with the ridiculous nature of his plot developments. For instance, Satyaraj's father, shown to be an orthodox priest, joins hands publicly with the villain because he doesn't like his son's cavalier attitude! Mega having a hidden agenda is acceptable but it is ridiculous when, after strutting around in skimpy clothing, she reveals herself to be a nun previously! Logic has no place in the movie either. One wonders how Mega could have gotten herself inside the police van where Satyaraj kills one of the criminals, to shoot the incident from different angles!

After the way the movie has proceeded so far, we don't have much expectations about the climax. But even by those lowered expectations, the climax is a letdown. It is quite violent and includes unnecessary deaths, an insipid encounter between the hero and villain and a clumsily picturised fight sequence between them - all hallmarks of a failed climax.

Almost everyone in the movie has overacted, making the entire experience quite irritating. Satyaraj's sarcastic comments too are overdone and don't make his character likeable. He is impressive as the mute villain though. Narayan Rao, playing his father, is the worst culprit, with his overdone expressions, exaggerated body language and loud dialog delivery. Mega is saddled with a vague role while Sangavi is barely noticeable as Satyaraj's wife in the flashback. Anandraj looks even more uncomfortable in the black makeup than Satyaraj!
