A series of murders take place in Avadi, Chennai, in the same pattern; stabbing by a knife. Each time the victim is paralysed before being killed. Police, led by IPS officer Krishnaswamy, suspect several people and they narrow down the killer by his age, which should be more than 70 years based on the writing style of a letter left behind by the killer while murdering his recent victim, an officer in the government treasury. The officer is killed by an old man who is later known to be Senapathy, a veteran Indian freedom fighter who was a member of the Indian National Army led by Subhas Chandra Bose, for threatening a poor old woman to bribe him to hand over compensation amount of ₹10,000 given by the government as her husband got killed in a riot.

Chandra Bose alias Chandru is a small-time broker stationed outside the Regional Transport Office at Chennai, who aids people in greasing the right officials inside the RTO for getting permits and licenses. His assistant Subbaiah, and Paneerselvam, an RTO official, are engaged in regular tiffs while Aishwarya, Chandru’s love interest and an avid animal rights activist, also battles it out with Sapna, a medical student and the daughter of an RTO official. Chandru hobnobs with Sapna and her family to secure a job as a brake inspector at the RTO. Aishwarya is irked by the fact that Sapna, as well as her mother, are exploiting Chandru’s situation, getting him to do grocery shopping, laundry, and almost every household chore. It is soon revealed that Chandru is none other than Senapathy’s son. They both had parted ways due to Senapathy’s excessive insistence on honesty and righteousness, which Chandru considers to be dead and worthless.
