The film begins by showing Rajni as Balu, a lavish spendthrift with a cavalier attitude towards life. Born to a rich father Chandrasekhar (played by VS Raghavan), Rajni has a rampant and aggressive behaviour and gets into confrontations wherever he perceives injustice. Worried about Rajni's behaviour, his father decides to send him to his friend and ex-militaryman Gangadharan's (played by Sendhamarai) village, to work for him for one year with a condition that Rajni will not reveal that he is the son of Chandrasekhar. Rajni slowly gets accustomed to the village life and learns to work hard and develops a good relation with Gangadharan and his family. During his stay, he spars with an arrogant rich girl, Sumathi (Madhavi). Madhavi assuming Rajni to be a poor villager tries to humiliate him and Rajni responds in kind.
