Prabhu comes into conflict with the underworld when he witnesses a brutal murder planned by a gang in Kasimedu in North Chennai by a smuggling don named Selvam (Kishore) and his accomplices. Prabhu finds out that his bike was stolen by a petty bike thief who turns out to be in connection with Selvam's egoistical younger brother Ravi (Daniel Balaji). Prabhu traces down the culprit (Sendrayan) and hands him over to the local police station. A formal complaint is lodged on the culprit on the same night. Later that night, Prabhu confesses to his family that his bike was stolen. His family is very upset but Prabhu's father assures them that the bike will be found in no time, having developed a feeling of respect for Prabhu after he had become responsible by going for a job.
