A young servant girl is raped, murdered and her body is dumped in a pond. The police accuse Unni Thampuran of murder and arrest him. Following torture methods, a confession is extracted from Unni Thamburan and the case is ready to be presented at the court.
Aniyan Kuruvilla, the public prosecutor, discovers flaws in the investigation and declines to fight. Convinced about Unni Thampuran's innocence, he switches sides and decides to fight for him. The prosecution hires a bent and a crooked lawyer Jagatheesh T. Nambiar and through a barrage of false witnesses and doctored testimonies, Unni Thampuran is found guilty and sentenced to life imprisonment.
Aniyan Kuruvilla, though beaten, doesn't lose hope and starts a private investigation of his own and discovers that a group of spoilt boys, Reji and his friends are responsible for the brutal murder. Incidentally, they also meet another woman who was raped by the trio. Reji is the son of a very powerful and influential woman, Accama.
Aniyan Kuruvilla reopens the case in court. Nambiar asks the court to dismiss the reopening as such move is very rare. He produces proof that the accused were in Palakkad attending a wedding and couldn't reach the spot of rape on the time as mentioned in the case file. Aniyan Kuruvila successfully proves the alibi as forged and thus helps to serve justice.
