text: In a village in South Kerala bordering Tamil Nadu lives a wealthy man named Raja Rathnam Pillai . Following the demise of his first wife, he marries Muthu Lakshmi Ammal so that the child from his 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 by the name 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 favor duly, as when Raja Rathnam's son ends up killing one of the children of the village, he takes the blame and leaves the village. Several years later, Raja Rathnam's two grown-up children, Rajaselvam  and Rani Rathnam , start fighting 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. As a result, Raja Rathnam is arrested, but dies of a heart attack while being taken to prison. After his death the two siblings call the family lawyer to read out Raja Rathnam's will in public. But to their surprise, they find that control of all the assets of their father have been given to a cattle dealer in Bellary, known by the name of Bellary Raja . 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, Rajaselvam and Rani Rathnam realize that Bellary Raja is actually their stepbrother. They try all they can to thwart him, so that they can regain control of their father's wealth. But Bellary Raja never falls for any of their attempts and he uses educated Raju 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. Towards the end of the movie, Rajaselvam and Simon Nadar get into an argument, which turns into a fight. Simon Nadar, who wants to harm Rajaselvam, betrays him and he is held by one of his old trade partners, who demands a lot of money for the release of Rajaselvam. Rajamanikyam comes to his rescue, pays the required amount of money to release Rajaselvam, and takes him home, where both of them settle their old enmities. The movie ends when Rajamanikyam, who is half-blind, says, "Now I have both eyes", signifying Raju  and Rajasel.
