The film starts with Kailasam (Ravi Kale), the somber bigwig who is performing the last rites of someone dear to him, but the appearance of Kottai (Jiiva) (first in the chaotic Koovagam festival and later atop a Veeranam pipe) swinging a scythe maniacally sets the tone for the rest of the film.
Cut to the flashback a few months ago: In Ramnad, Kottai’s mother (Saranya Ponvannan) is cutting down logs and boasting about her son: he is a god who deserves to see the outside world and derive its benefits. Kottai journeys to big bad Chennai in company with Vellaiyan (Ganja Karuppu), who dances with every Karagattam dancer on the roadside, makes lewd jokes, and appears to have only one thing on his mind. They end up at the massive home of Kailasam, the local terror who slices up people whenever he can. However, our heroes are unaware of the fact.

Vaanavaraayan (Rajinikanth) is a feudal chieftain, adored and respected by the people of his village. 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. Vallavaraayan then convinces the priest of the village temple to mix poison in the holy water that Vaitheeswari drinks. As a result, she becomes incapable of conceiving a baby. 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 honour. 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, Vaanavarayan attacks Vallavarayan and spares his life after giving him a sermon on how to win the heart of the people.
