In a village in Southern Kerala bordering Tamil Nadu lives a wealthy and respectful businessman named Raja Rathnam Pillai. Following the demise of his first wife, he marries Muthu Lakshmi so that Raja Selvam, 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 realises 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, Selvam and Rani Rathnam (Muthu Lakshmi's daughter), quarrel for their father's wealth. Rajaselvam, aided by his childhood buddy Simon Nadar 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 slain 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, Raja Rathnam dies of a heart attack - sitting inside the police van - while being taken to the prison.
