In a prelude, the families of SP and Bhavani feud bitterly while SP and Bhavani fall in love. SP's father is accused of murdering Bhavani's father, which fuels a lifetime of mistrust. To prove his father's innocence and heal the rift, SP mortgages his own house to finance Bhavani's factory, hoping to make amends. Bhavani's desire for revenge still simmers beneath their romance.

SP confronts Bhavani's uncle, trying to reveal the truth about the murder. Bhavani refuses to believe him, clinging to her version of events. In a pivotal moment, SP declares he no longer loves her and vows to remain a bachelor forever.

The story shifts to the present, where SP and Bhavani wage a legal battle over the house. SP wins, reclaiming his home, much to Bhavani's fury. She threatens to destroy him, setting the stage for ongoing conflict.

SP has become a successful businessman and now lives near his stepsister Parvathi, whom he supports. Parvathi is unaware that SP is her brother, living next door and relying on his help. The household dynamics begin with a lighthearted, comic tone as Mayil and friends adjust.

Gowri enters the hostel where Parvathi stays, trying to win SP's heart, while SP continues to sponsor Parvathi's studies. SP tells Gowri that Parvathi is his sister, but Gowri remains a thorn in SP's side. The seeds of rivalry deepen as Gowri's true ties begin to blur.

Gowri invites Parvathi to a birthday party and reveals that SP has been funding her. Bhavani arrives and takes Gowri away, exposing the sisters' fraught relationship. Rivalry between Gowri and Bhavani heats up, setting the stage for future confrontations.

Durairaj and his gang abduct Parvathi, prompting Kannan to intervene. Kannan helps rescue Parvathi and also brings Gowri back, foreshadowing his own role in the family drama. SP declares that he will sponsor the girl who loves him just as he sponsors the girl he loves.

SP and Mayil catch Kannan attempting to reach Parvathi on the balcony, confirming their mutual love. SP makes Kannan promise to be faithful and orchestrates the marriage between Kannan and Parvathi. He then transfers his assets to Parvathi's name, believing she will need them.

SP invites Parvathi to move into his house while Kannan and Cheenu relocate to a guest suite. Parvathi shows affection toward Kannan, but SP steps in to clarify their sibling bond and protect Parvathi's future. The dynamic shifts from romantic potential to familial ties.

SP explains the complexities of the situation and urges Parvathi to see him as a brother. Parvathi recalls her mother's blessing to forgive SP, and they reconcile as siblings. The moment reinforces the plan for Kannan and Parvathi's future together.

As wedding festivities begin, Bhavani, Durairaj, and Veerapandi challenge SP's rights over Parvathi. A lively power struggle ensues as property and loyalties are contested, threatening to derail the marriage. SP remains steadfast in protecting Parvathi's happiness.

The truth comes out as Bhavani's husband admits the murder was motivated by money but born of love. Bhavani realises her mistakes and apologises to SP, offering Gowri's marriage to SP as a resolution. The moment reframes the stakes of the family feud.

SP, after initial hesitation, agrees to Gowri's proposal to marry him, recognizing it as the path to harmony. He asks everyone to proceed with Gowri's marriage, ending the long conflict. The film closes with Gowri marrying SP and a reconciled family.
