The series centers on Renuka, the adopted daughter of Swamiappan and Sivagami. Swamiappan, a retired mechanic, and Sivagami, dote on her and consider her as their favourite child, even though she is adopted. Swamiappan's household includes his two biological sons, Natesan, an accountant, and Manickam, who works in a factory, their respective wives Parvathi and Maya as well as Natesan's and Parvathi's daughter Shraddha. Swamiappan's widowed sister Mangaiyakarasi and her children; Shanmugam, an autodriver, and Malar, a budding athlete, also live in the Swamiappan household.

Shanmugam has a one-sided love for Renuka and does whatever he can to help her. However, Renuka is in love with her cousin Arjun, who is the son of Sivagami's younger brother Dayalan, a reputed lawyer and industrialist, and Viji. Dayalan is money-minded and cruel, and hates Renuka, looks down upon Swamiappan for his lack of money, while treating Shanmugam worse than a servant due to his lack of education. During Swamiappan's 60th birthday celebration, Swamiappan proposes to Dayalan to fix the marriage between Renuka and Arjun, but Dayalan turns the proposal down, claiming that he cannot marry his son to someone whose past is unknown. This forces Swamiappan and Sivagami to disown Dayalan and his family, while Renuka begins to keep a distance from Arjun, even though both still have feelings for each other.

Following Renuka's graduation, Swamiappan is keen on her pursuing higher education, but she hesitates initially due to lack of financial support. Natesan, as well as Maya, who are both earning well, refuse to help her, jealous of the love and support she receives from the rest of the family despite being adopted, much to the chagrin of their respective spouses Parvathi and Manickam, who dote on her. Natesan and Maya also do not allow Parvathi and Manickam to help Renuka financially. However, when Dayalan insults Renuka in front of her entire family due to a misunderstanding involving Arjun, Renuka challenges him that she would study law and become a more successful lawyer than him.

She joins a law college and also works as a typist at a xerox shop part-time to pay her college fees. It is soon revealed that Renuka is the biological daughter of Panjali, a famous lawyer and social activist. Panjali had abandoned Renuka in a temple when she was an infant for hitherto unknown reasons. Swamiappan noticed Renuka and decided to take her home and raise her as her own child. However, both Panjali and the adult Renuka do not know that they are mother and daughter, though they cross paths a few times.
