Summary
Kannamma is a pure-hearted girl who is looked down upon by her beautiful stepsister, Anjali, and step-mother, Bhagyalakshmi, due to her dark complexion. Her father however supports and praises her kind nature. Soundarya is a business tycoon who is obsessed with Eurocentric beauty and when Anjali wins the Miss Chennai competition, she arranges a marriage between her and her younger son, Akhilan. Akhilan takes an instant liking to Anjali, but Anjali likes his brother, Bharathi. During this love triangle, Bharathi and Kannamma frequently cross paths, and Bharathi ends up falling for her.
Anjali attempts to blackmail Bharathi into marrying her by threatening suicide, but Bharathi approaches her father to ask his permission to marry Kannamma, and reveals that he is infertile. He then asks him to break the news to Kannamma, and on the condition that she is okay with that, he will marry her. However, Kannamma's father does not tell Kannamma about his infertility, and she consents to the marriage. Kannamma is ecstatic that she will be marrying a good-hearted man. On Anjali's birthday, Bharathi marries Kannamma, enraging both his mother and Anjali. Akhil and Bharathi's father Venu are happy. Soundarya allows Kannamma into the house after insulting her. Anjali marries Akhil and schemes to get rid of Kannamma so that she can divorce Akhil and marry Bharathi, but is thwarted by Soundarya, and later starts to fall in love with Akhil.
Dr. Venba, a coworker madly in love with Bharathi, schemes to break up Bharathi and Kannamma as she wants Bharathi for herself. Kannamma consults with Venba as she is having trouble conceiving, but Venba uses this in her scheme, convincing Bharathi to make it look like she is the reason why they cannot conceive. During a reunion, Varun, a friend of Kannamma, attends, and Venba plants the idea that Kannamma is having an affair with Varun in Bharathi's head.
Having learned that Kannamma is allegedly infertile, Soundarya calls on Bharathi to remarry, with Venba happy that she can be the second wife, but Soundarya wants him to marry someone else. Soon after, Kannamma starts showing symptoms of pregnancy, and later shows a positive pregnancy test to Soundarya, so as to stop her from trying to find Bharathi a new wife. Venba hires a killer, Durga, to kill Kannamma, but the killer later realizes that Kannamma is a good person and he sticks around to stop Venba from trying to kill her and meddle in her life.
It is revealed that Venba killed Bharathi's ex, Hema, and Durga comes clean to Kannamma about his original intentions, but says that Bharathi is the one who wanted her dead and not Venba, as he is in love with Venba. Kannamma attempts to leave the house and reveals to Soundarya that her son is trying to kill her and her baby. The family confronts Bharathi, who says he is not trying to kill her but reveals that he cannot be the father.
Kannamma goes to her parents house and yells at her father for not telling her the truth about his alleged infertility and she leaves. The family tries to get Bharathi to do another fertility test but is stopped by Venba. Kannamma gives birth to twins (Hema and Lakshmi), but Soundarya takes the darker-skinned of the twins unbeknownst to Kannamma, as she wanted to help Kannamma. Soundarya takes the baby home, and saves Bharathi's life by crying which gets him to tend to her, as a chandelier falls. He then takes an interest in the baby and names her Hema, after his ex. Kannamma stays with the nurse, Thulasi. Venba tries to marry Bharathi and almost succeeds but is thwarted by Soundarya.
