Rajinikanth, Meena, Goundamani
Vaanavaraayan (Rajinikanth) plays the role of a feudal chieftain, adored and respected by his village people. He lives with his grandparents (M. N. Nambiar & Manorama).
Following his advice, they abstain from voting in the elections and instead, pool the money given by the candidates to get themselves some basic amenities. Vallavaraayan (Napoleon) is his arch enemy. Their enmity is further sharpened when Vaanavaraayan wins the hand of Vaitheeswari (Meena), whom Vallavaraayan had also wished to wed. So Vallavaraayan convinces the priest at the temple to mix a poison in the holy water that Vaitheeswari drinks.
As a result she becomes incapable of conceiving. But surprisingly, Vaitheeswari soon becomes pregnant-though she has pretended with the help of the mid-wife (S. N. Lakshmi), to do so to uphold her husband's honor. She takes poison and kills herself unable to bear the grief of being incapable of giving her husband a child and on her deathbed makes Vaanavarayan swear to take Ponni (Aishwariya) as his wife.
Vaanavarayan however refuses until Ponni agrees to marry Sembattai ('Thalapathi' Dinesh)- Vallavarayan's hechman-who abandons her to Vallavarayan's vice. Infuriated Vaanavarayam attacks Vallavarayam and spares his life after giving him a sermon on how to win the heart of people.
