In a village in Southern Kerala bordering Tamil Nadu lives a wealthy man named Raja Rathnam Pillai (Sai Kumar). Following the demise of his first wife, he marries Muthu Lakshmi Ammal so that the child from his first marriage will not grow up without the love and care of a mother. Unknown to him, Muthu Lakshmi already has a son, whom she calls Muthu.
On the night of the wedding, Muthu knocks at the door of Raja Rathnam Pillai, demanding that he be shown his mother. Once Raja Rathnam comes to know the truth, he takes Muthu into his care, giving him love, affection and a new name, “Rajamanikyam”. Muthu returns the favour duly, as when Raja Rathnam’s son ends up killing one of the children of the village, he takes up the blame and leaves the village.
Several years later, Raja Rathnam’s two grown-up children, Raja Selvam (Manoj K. Jayan) and Rani Rathnam (Sindhu Menon) (Muthu Lakshmi’s daughter), start quarrelling for their father’s wealth. Rajaselvam, aided by his childhood buddy Simon Nadar (Ranjith) also notches up a plot to frame his own father in a murder case. Raja Rathnam is implicated in a sensitive political murder. As a result, Rathnam is arrested and remanded. While taking Rathnam to the prison from the premises of the court, a wide scale altercation erupts – between Rathnam’s supporters and the sycophants of the slained politician. Amidst the chaos, a huge stone is pelted at Rathnam – severely injuring him. (The stone is pelted by the actual assailant). Witnessing the riots, Rathnam dies of a heart attack – sitting inside the police van – while being taken to the prison.
After his death the two siblings are summoned by the family lawyer to read out the provisions of Raja Rathnam’s will. But to their surprise, they find that control of all the assets of their father have been transferred to a cattle dealer in Bellary, known by the name of Bellary Raja (Mammootty), a billionaire. They fail to recognize that Bellary Raja is none other than Rajamanikyam. How Rajamanikyam returns to his home town to unite the warring siblings forms the rest of the story.
During the course of the movie, Raja Selvam and Rani Rathnam tries to thwart Bellary Raja in order to regain control of their father’s wealth. But Bellary Raja never falls for any of their attempts and he uses his adopted brother and Manager, educated Raju (Rahman) to stabilize the assets of his stepfather and prevents it from getting into the hands of his siblings, thereby preserving it. Raja effectively uses the help of his thug friends to restore order in the establishment. Bellary’s identity of Rajamanikyam is revealed by himself at a crucial juncture and revelation stuns the entire family. Simon and Raja Selvam sends a goon to kill Bellary from his blind side. However Bellary thwart the attempt, causing him minor wound.
Differences emerge between Raja Selvam and Simon Nadar regarding a financial liability. Simon betrays Selvam him and he is held captive by a boorish Tamil moneylender – who demands the repayment for the release of Raja Selvam. Rani – unaware of the latter developments – blames Manikyam in order to deny them their claim over their father’s wealth. Manikyam comes to the rescue and pays the required amount of money to release Raja Selvam. He emotionally narrates his hardships and love for his siblings – stirring the emotions of his mother and siblings. Feeling deeply disappointed – on being unable to fulfill his father’s wish to unite their family, Manikyam prepares to leave for Bellary.
At night Raja Selvam, being absolutely drunk and weeping comes to Manikyam’s house and apologizes for all his past deeds and embraces him – burying all differences. He asks Manikyam not to leave them. Manikyam is deeply moved and laments that, Raja Rathnam was unfortunate as he ‘left early’ (An untimely death) and he could not witness the conciliation. Varghese, a close confidant of Raja Rathnam, reveals that, Rathnam was rather ‘packed off’ (A murder) – resulting in the narration of the deceit and Manikyam and acolytes go in search for the actual assailant. When the latter individual is caught, he reveals the main conspirator, Simon Nadar. Towards the end of the movie, Raja Selvam and Simon Nadar gets into a duel. Selvam, beaten badly by Simon Nadar and his goons was about to be killed. However, Bellary and his men came to rescue and fight off Simon.
At the Climax, Bellari releases a bull towards Simon for killing his father and trying to destroy his family and kills him. He reunites with Rajaselvam and takes him home. The movie ends when Rajamanikyam, who is half-blind, says, “Now I have both eyes”, signifying Raju (whom he considers a brother) and Raja Selvam.
