The film starts with the police arresting Aadhikesavan's (Suresh Gopi) men suspecting them for burning an MLA's wine shop. The MLA sends a false evidence to the court against Aadhikesavan. But Aadhi sends Dheenadhayalan aka Dheena (Ajith Kumar) who is actually his adopted brother to attack the false evidence. Later some people complain to Aadhi that the MLA had removed the breakwire from a schoolvan due to rivalry between his school and their school leading to the death of many children. Aadhi asks Dheena and his henchmen to cut the hands of the MLA and his men especially the right hand and Dheena completes his task.
