Gowri returns to the village after studying in the city and initially misjudges Vetrivel as a servant in Paramasivam's house. She soon learns that he is Paramasivam's son and a respected figure in the community. The two gradually grow fond of each other, and Paramasivam and Parvathy begin planning their marriage.

Subramani returns to the village after his studies and has a dangerous fall when he slips from a mountain while photographing a waterfall. Gowri hears his cry and helps, and the villagers rescue him. Grateful and smitten, Subramani tells Vetrivel that he wants to marry Gowri, prompting Vetrivel to make a selfless choice to support his brother.

Vetrivel, showing his generosity, convinces Paramasivam and Parvathy to allow Subramani to marry Gowri first, even though Vetrivel loves her. He explains that family harmony matters more than his own happiness. The elders reluctantly agree to his proposal.

Gowri and Subramani marry in the village after Vetrivel's sacrifice and the elders' consent. The ceremony binds Gowri to the Vetrivel household and deepens the ties between the two families.

Chinna, who works in Paramasivam's home, drinks one night and reveals to Vetrivel's parents the truth about his sacrifice. The revelation triggers the decision to marry Vetrivel to Rasathi, Parvathy's relative, to stabilize the family.

Rasathi's father Maniyaandar and grandfather Angaala Thevar harbor a vendetta against Parvathy and Paramasivam and openly want them killed. Their malice adds danger to the planned marriage and to the village's peace.

Ponnambalam, who dislikes Vetrivel, tells Subramani that Gowri and Vetrivel are in an illegitimate relationship, inflaming Subramani's anger. The rumor threatens to derail the fragile harmony between the two families.

Gowri suddenly vomits and faints; Ramakrishnan informs everyone happily that Gowri is pregnant, shocking Subramani who wanted to have children after Vetrivel's marriage. Subramani's doubts erupt, and he shouts at Vetrivel before leaving home.

Paramasivam and Parvathy scold Subramani for his rash behavior and doubting the family plans. As the confrontation unfolds, a flashback is shown that reveals Vetrivel's true lineage and his deep bond with Paramasivam and Parvathy.

In the flashback, it is revealed that Vetrivel is the son of Vasudevar Ayya, a wealthy man in the village. Paramasivam had once worked as a driver for Parvathy, and their marriage is tied to a history of danger and loyalty. Vasudevar Ayya fights to protect them, even as his own enemies try to destroy the family.

Vasudevar Ayya is killed by Angaala Thevar and Maniyaandar while defending the couple, and before dying he orders Parvathy and Paramasivam to stay out of trouble and to raise Vetrivel. He leaves them with the inheritance and responsibility to protect him.

A doctor later checks Gowri and confirms that she is not pregnant, dispelling the rumor. Subramani realises his mistake and apologises to Vetrivel and Gowri for his earlier doubts and harsh words.

Gowri, moved by Vetrivel's selflessness, asks that he marry Rasathi to fulfill the family's plans. Vetrivel agrees, valuing the happiness of his family and Gowri's wishes over his own. The arrangement lays the groundwork for the final union.

Vetrivel marries Rasathi with the blessing of Rasathi's father, who is won over by Gowri's request and Vetrivel's steadfast loyalty to his family. The marriage marks a resolution to the village's conflicts and a peace for the families involved.
