Police inspector Umar (Rahman) works on the case. The story is narrated in flashback. Rama Krishna is an apparently mentally affected teenager (later diagnosed as autistic), living dependent on his mother Saradha (Saranya Ponvannan). His over compulsive adoration for his mother lands her in various problems. Raam is provoked easily and tolerates little wrongdoing around him. Next door lives Karthika (Gajala), daughter of a Police Sub-Inspector Malaichamy (Murali). She falls for Raam, but upon telling him how she feels, gets a blunt response from him. One day, Saradha is found brutally murdered. Umar, interrogating various personalities for the case, grills each and every person possibly connected to Raam and the teacher. Every possible motive that Raam might have for murdering his mother is explored. Furthermore, Raam's neighbours, the sub-inspector Malaichamy and his children are summoned by Umar for interrogation, much to their irritation. The police eventually find out that it was Karthika's brother (Kunal Shah), who committed the murder, in fear that Saradha would tell his parents about his drug addiction habits. When Umar confronts him and forces him to surrender, Karthika's brother fatally wounds him and escapes, injuring his father in the process as well. On finding the hideout of her brother from his friends, Karthika tries to plead with him to surrender. But he refuses to do so and ties up Karthika. Raam, seeking vengeance , finds the hideout.
