Mohan Kumar is a school teacher who's loved and respected by all his students and is a happily married man, with two kids, they all lead a simple yet a contend life. One such day, the family unintentionally witness a murder; a gang of four men attack and kill a couple at a park. His daughter freaks out by the incident, while his son records it in his phone. A visibly upset Mohan urges his family to disperse from the place as quietly as possible.
A while later, the gang finds out about the family standing witness to their crime, and decides to kill them all. Anyhow, Mohan and his two children escape with injuries, while his wife Shriya Sri dies on the spot. After Mohan recovers, he files a complaint against them, but the criminals themselves first surrender and then soon obtain a bail. Mohan feels devastated as they are left free, but as he is a person who obeys rules and regulations he stays quiet believing that he will get the proper justice he yearns for.
Meanwhile, few of his students witness the same set of criminals murdering another girl, and they immediately report to Mohan, he gets furious that they have committed another crime even though they have given another chance and decides to deal this situation on his own and plans to kill them all. The rest of the plot revolves around whether he gets the revenge he seeks for.
Mohan Kumar's performance is filmy and okay, similarly Shriya Sri and rest of the cast has also done the same. Director Bagavathy Bala has attempted to make an action commercial movie, and has tried to convey the message of how a teacher should influence the minds of students, but in order to do so he has used the age old stroyline, with poor quality and filmy screenplay. The director is also the cinematographer and his frames are decent. Raj Baskar has scored the music and while his songs are cringeworthy, he has done a comparatively better job with the background music.
In short, Neri, is okay.
