Ganesan (Harikumar) and his friend Gilaki (Soori) sell arrack and ganja in Bodinayakkanur and they work for the heartless ruffian Thiruvaachi (Ravi Shankar). Ganesan and Gilaki often go to jail for petty crimes and Ganesan has a mentally-challenged brother Kottaiyan who lives in a special home. One day, Ganesan comes across the nurse Raji (Arundhathi) who cares and shares for others and he falls in love with her. When Ganesan reveals his love, Raji insults him for being a rowdy and advises him to become a good man. Her words shook him so much, that Ganesan all of a sudden has an epileptic seizure in front of her and no one came to help him. Ganesan then decides to earn an honest living but Thiruvaachi who has a grudge against Ganesan tries to stop him. Meanwhile, Thiruvaachi wants to marry his cousin Raji and confronts Ganesan. In the past, Thiruvaachi was the son of the wealthy man Azhagar (L. Raja) while Ganesan was the son of their servant Manikkam (V. Venkatesh). Being constantly and unfavourably compared with Ganesan who was academically-inclined, Thiruvachi had developed a hatred for Ganesan and he had slowly become a wastrel. One day, Thiruvaachi stabbed to death his own father Azhagar in front of Ganesan and a shocked Ganesan had his first epileptic seizure but before dying, Azhagar requested Ganesan to endure Thiruvachi's evil deeds for the good of Kottaiyan. Thiruvaachi left the place and blamed Ganesan for killing his father. The innocent Ganesan spent time in jail and he then became Thiruvaachi's henchman. Back to the present, Ganesan fights back and defeats Thiruvaachi. Raji eventually accepts to marry a reformed Ganesan and they get engaged with the blessings of Raji's mother, Gilaki, Gilaki's newly married wife Annakili (Janaki) and the villagers. Thiruvaachi then abducts Annakili and he threatens to rape her unless Gilaki gives Kottaiyan up. Gilaki surprisingly makes the exchange and he then feels guilty of betraying his best friend. The next day, Gilaki is found hanging from a tree and Annakili reveals everything to Ganesan. Ganesan sets out to find his brother but Thiruvaachi mercilessly kills Kottaiyan. Ganesan and Raji track Thiruvaachi down and they find the dead body of Kottaiyan. Ganesan begins to have an epileptic seizure but he manages to control it and Thiruvaachi attacks the couple. The film ends with Ganesan killing Thiruvaachi.
