InbaSekar grew up to be a goon as his brother Gunasekaran had left him to fend for himself, and he had no option of earning. He loves, marries, and abuses his wife Sashi. He gets into a contract under Guna's recommendation to run errands and work as a hitman for Selvanayagam, a politician.
Michael is an influential student leader who wants politicians like Selvanayagam to keep away from college elections. Michael is in love with his neighbour Geetha, who lives with her uncle and aunt. Selvanayagam is worried when he hears news of students standing in the election. He uses every possible tactic to get them out of politics. Firstly, he provides a scholarship to study at a prestigious foreign university to Michael. When Michael refuses the bribe, Inba takes control under Guna's orders. Inba beats some students but faces very strong retaliation from Michael and other students. Inba and his thug friend Dilli meet Michael face-to-face and fall into a tussle after Inba threatens the latter to leave politics.
