In
Chennai, Raja is the only son of Chandrasekhar, a retired colonel who raises him very strictly. Chandrasekhar decides to get Raja married to his friend Viswanathan's daughter Indhu. Vishwanathan is a tea estate owner and one of the richest men in
Ooty. Raja misunderstands another girl as Indhu (Chandrasekhar's nephew Shankar switched Indhu's photo with another girl's) and decides to run away from Chennai to escape the
forced marriage. Unknown to Chandrasekhar, Shankar plans to grab his properties by triggering Raja to leave the house. Raja reaches Ooty, where he meets Vasu, a
con artist, and despite initial setbacks both become friends. One day, Raja sees Indhu in Ooty and gets attracted towards her, not knowing that she was the girl fixed for him by his father. Raja follows Indhu and finds her home. Later Raja secures a driver job in Viswanathan's home to woo Indhu. Raja gives his family ring to Vasu to prevent him from disclosing the truth to Viswanathan, but Viswanathan misunderstands Vasu as Chandrasekhar's son as he wears the ring now. Viswanathan brings Vasu to his home and introduces him as Indhu's fiancé. One day, a gang tries to attack Vasu, but he is saved by Raja, which makes him understand that there is someone looking out to kill him, so Raja decides to remain incognito as a driver to unearth the reason behind the goons trying to attack him. Viswanathan informs Chandrasekhar that his son is found but asks him not to come immediately to see him as he dislikes his father. Meanwhile, at Ooty, Raja tries to impress Indhu, while Vasu is attracted towards Viswanathan's personal secretary Meena. Slowly, love blossoms between Indhu and Raja. Suddenly, Chandrasekhar comes to Ooty to Viswanathan's home to meet Raja. A problem erupts as Raja is incognito as a driver. Both Raja and Vasu try to manage by roaming together for a few days so that they can convince both Viswanathan and Chandrasekhar. Meanwhile, Shankar gets furious upon knowing that Raja is found. He befriends Kasinathan, who is Viswanathan's twin brother. Kasinathan is a criminal who has just been released from jail. They kidnap Viswanathan, and Kasinathan comes to Viswanathan's place so that he can enjoy all the properties and wealth. Doubt erupts for Raja and Vasu upon seeing Kasinathan as he spends money lavishly, compared to the stingy Viswanathan. Raja and Vasu secretly follow Kasinathan and finds the whereabouts of Viswanathan and the plan behind his kidnap. Raja is shocked to see his cousin Shankar there as he is the mastermind behind all the events. A fight follows, where in the end, Shankar and Kasinathan get arrested. It is also revealed that Raja is the son of Chandrasekhar. Raja unites with Indhu, while Vasu unites with Meena. == Cast ==
