Govindan (Manivannan) is a thief who has two children. Aadhi (Pasupathy) and Mathi (`Chiyaan` Vikram). Years go by and the two, Aadhi and Madhi, decide to stop stealing and mend their ways and lead a hardworking life along with their father. They migrate to neighboring village and meet a retired agricultural officer, Chidambaram (Vijaya Kumar) who is in deep debts and is under pressure from the village`s landlord, Kalingarayar (Murali) to clear his debts. In efforts to help Chidambaran, Mathi confronts Seetha Lakshmi (Asin), Kalingarayar`s daughter, who comes to collect the money Chidambaram owes her father. Seetha Lakshmi starts to acquire a liking for Mathi but keeps it hidden due to her father`s atrocious temper. In an attempt to teach Kalingarayar a lesson, Mathi forcibly ties the mangalsutram around Seetha`s neck. Kalingarayar, realizing his daughter`s love for Mathi, comes down to arrange a grand re-marriage between the two.
