Raja (Prabhu) arrives in town as the new teacher and is offered a place to stay at the home of the trustee of the school, Sivagami (Srividya).

Her father, Somasundaram (V. S. Raghavan) was the town leader and opposed the match due to Veerayya's illiteracy and lack of wealth.

Periyadurai smuggles drugs, prints counterfeit cash and has murdered townspeople in his bid to become rich and powerful.

He's assisted in his misdeeds by his younger brother Chelladurai (Sivachandran), mistress Mayilu (Kovai Sarala) and right-hand man Papo (Vennira Aadai Moorthy).

This sets Sivagami, Veerayya and Raja against Peryiradurai as the trio work together to uncover the depths of his misdeeds and bring him to justice.
