His altruistic views and public appearances awarded him the image of a supreme hero long before this film's release. However, the huge wave of popularity and the image-building resulted in increasing the expectations for Naayaghan. Though Naayaghan is J.K. Ritheesh's second venture, the film has experienced a lot of pre-release hype and hoopla which it certainly lives up to. Also, as opposed to popular practice, Ritheesh is not cast as the film's hero; he is just a tough cop devoid of the super-hero aura, a cop who goes about doing his job in a straightforward manner.

Dr. Sandhya (Sangitha) and her husband, both practising physicians, happen to witness and video record a crime. This video footage contains evidence of a gangster group kidnapping and raping a lady. The gangster (Anandraj), coming to know about the recording and planning to obtain it by any means, abducts Dr. Sandhya and her young son. However, the smart doctor manages to escape from their custody. She also boldly tries to get in touch with somebody outside for help. Spotting a telephone line in the narrow booth she is thrown into, she manages to make a random call to an unknown number. But before the line is activated and she can convey the message, Sandhya is attacked by the thugs and she runs away from the place, carrying the video evidence and breaking the phone connection.

Sandhya's anonymous call is received by Shakthi (Ramana) a cab driver while he is on his way to the Police Commissioner's office. Shakthi too is stuck in a serious predicament by the timing of the call. When he receives the call, he is eloping with his fiancée (Keerthi Chawla); to escape from a family feud, Shakthi is planning to seek police help and support to conduct the wedding. Too distracted by his own woes and unable to comprehend the details of the caller and the call, Shakthi does not follow up the mysterious call.

However, after a long struggle, daring Dr. Sandhya reaches the Commissioner's office and files a complaint. Encounter specialist Guru (J.K. Ritheesh) is appointed to handle the case. Predictably, the hide-and-seek between Sandhya, Shakthi and Guru ends there. All three realize the actual connections between the day's events and people. How Guru apprehends the criminals forms the rest of the story.

First, congratulations to J.K. Ritheesh for choosing to star in a less-than-ideal story. His character is nicely drawn. He looks completely comfortable in his role and his attitude appears very realistic, particularly when he is shown ignoring Dr. Sandhya's case and getting involved in other matters concerning politicians. It showcases Inspector Ritheesh's commitment and his clear objective. Sangitha has done a good job in Naayaghan. Anandraj's dual role and Pandiarajan's impressive cameo are other noteworthy features.

Director Saravanasakthi has spun the story adding a lot of interesting thrills, twists and turns. For example, Shakthi and Sandhya travel in the same share-auto and Sandhya is desperate to get in touch with the cops. Having seen the video clipping, Shakthi finds Sandhya to be faintly familiar; also, when Sandhya is close to a person (Shakthi) who can be of help, she barely realizes it. Yet throughout the auto journey, both of them make no move to identify or communicate with each other. This particular scene indeed steps up audiences' excitement. The script is taut and there is absolutely no dull moment in the movie.

Stunts in the film are stunning, including the amazing boat-chasing sequence. 'Nila Nila' in Mariya Manohar's music is a soothing melody.
