Arul (Vikram (actor)), who works in a mill, is the third son of four brothers in a family of goldsmiths. Once, Arul's brother steals a chain due to financial circumstances. Arul took the blame for it, was labelled as a thief, and was seen as a black sheep by his father Bala Aasari (Vinu Chakravarthy). Thus, he vows never to make a gold ornament ever again, so he takes up a job and pays for his expenses. Kanmani (Jyothika), who moves into the opposite house, begins by playing tricks on Arul but eventually falls for his character. Arul does not believe in love and keeps his distance from her. One day, when Bala scolds Arul in the temple, Kanmani stands up for Arul. Bala insults Kanmani by telling her, "Arul's siblings are keeping quiet. Why are you making noise as though you have slept with him?" Soon, Arul marries Kanmani. The setting up of the party office of the ruling party forces Arul to lock horns with MLA Gajapathy (Pasupathy) and his brother Minister Sethupathy (Kollam Thulasi), the party leader. How Arul defeats the bad guys form the rest of the story.
