Shanmugam, a veterinary doctor, lives in the city with his wife Valarmati and their two children. In school, Shanmugam was in love with his classmate Dhanalakshmi, but fate had forced them to go their separate ways, with Dhanam being forced to wed her brother-in-law (Sayaji Shinde). One day, Shanmugam spots Dhanam, who, having lost her husband, now lives a life of poverty on the platforms with her son Balu. After an unsuccessful attempt to find her a job in a friend's house, he hires her as their servant-maid. However, memories of the past start to create a tension between Shanmugam and Dhanam, despite their attempts to maintain a distance.
One day, Valarmati finds out from Shanmugam's old classmates how they both were in love when they were young, and she starts fearing that Shanmugam will leave her and her children for Dhanam. Valarmati becomes so distraught that she even humiliates Dhanam at a party organised by one of their friends. When they return home, Valarmati confronts Shanmugam, and an argument ensues. Dhanam overhears their argument and silently goes to bed. The next morning, Dhanam and Balu are nowhere to be found. When Shanmugam searches the house, he finds a letter written by Dhanam saying that she wants Valarmati and Shanmugam to be happy and that she doesn't want to come between them. Soon, Valarmati realises the truth and wants to bring Dhanam back home and ask her for her forgiveness.
Shanmugam searches high and low for them and at last finds Balu in an orphanage. The matron informs them that his mother had left instructions that her son should remain at the orphanage till her return. However, when the matron questions Balu, he replies that he wants to go with Shanmugam and stay in their house and to tell his mother that he is there when she returns. The matron agrees and lets him go. At the beginning of the movie, it is mentioned that Balu has been adopted by Shanmugam but still continues to call him "Sir" and never "Father or "Dad". As Shanmugam leaves for home from the orphanage, he mentions that he is still searching for Dhanam's whereabouts to that day.
