Sadagopan [Vinu Chakravarthy] is the steadfast patriarch of a bustling family who has four daughters and one son. He views his son as the obvious heir and asset, while he treats his daughters as a burden on his head, driven by a belief that their education should lead to a secure, dowry-free future. With the help of his Iyer priest friend Venniradai Moorthy, he embarks on a mission to find grooms for his three educated elder daughters who fit his strict dowry conditions. He insists on marriages that require no dowry and believes that the right match should be determined by status and utility, not affection or compatibility.
To fulfill this plan, Sadagopan identifies three surprisingly underqualified suitors who nonetheless meet the letter of his dowry rule: for elder daughter Lakshmi, Murugesan is a marriage catering cook; for second daughter Sundari, Sekar is a Corporation pesticide-spraying worker; and for third daughter Indra, Muthupandi is an auto-rickshaw driver. He pushes his daughters toward these potential husbands, paying little heed to their own desires, concerns, or readiness to wed. The first two daughters reluctantly accept their matches, while Indra holds out, wanting to meet her groom personally to judge whether he is truly a good fit.
Indra eventually learns the truth about her would-be husband: Sadagopan spins a false tale, telling her that her groom is a businessman running an automobile shop. The deception stirs a storm of emotion, because the real job of Muthupandi is far from the businessman image she was prepared to accept. Although Lakshmi and Sundari marry their grooms, Indra remains unsettled until she confronts the reality of the arrangement. The three couples move into their husbands’ homes, and a troubling pattern emerges: despite no dowry being exchanged, the men seek to rely on their wives’ property and press for money to start their own ventures, a request the wives reluctantly agree to in the face of economic and familial pressure.
Meanwhile, Sadagopan’s son proves to be deeply selfish, clinging to his father’s wealth and resisting the idea of sharing it with his sisters. He marries a powerful politician’s daughter, and at the wedding the newlyweds inflict insults upon the grooms, banishing them from the hall and further enraging the men. The husbands vent their anger by pressuring their wives to secure money from their parents, intensifying the strain in the domestic sphere. Meenakshi, the mother, promises to speak with her husband to secure the needed funds, but a troubling turn comes when her own son schemes to claim all the family property in his name, leveraging his father’s blind love as a shield.
Meenakshi’s struggle to defend her daughters’ rights leads to a devastating outcome: she suffers fatal brain damage, leaving Sadagopan to confront the consequences of his biased choices. He begins to see the damage his preference for a male heir has caused—a realization that his son’s loyalty to the in-laws has pushed him away from his own family. The father slowly recognizes the error of his ways and resolves to redeem the situation by arranging a arranged marriage for his youngest daughter to a well-qualified, respectable suitor, hoping to grant her a peaceful and legitimate future.
This decision enrages his son, who views the wealth as his, and a fierce clash erupts, culminating in Sadagopan being expelled from his own home along with his elder sister. In the turmoil, Indra, Lakshmi, and Sundari file petitions in court seeking their rightful shares of their father’s property, inviting tension and a stern test of the family bonds. Guided by the counsel of their father-in-law, the brother attempts to broker a deal that would secure the sisters’ signatures in exchange for releasing the property dispute, but Indra sees through the deception and refuses to sign.
Realizing their shortcomings, the three husbands soften their stance and choose to support their wives in the wedding of the fourth daughter, insisting that the sisters’ happiness should not be compromised for wealth. The brother escalates the conflict on the wedding day, forcing a confrontation that ends with Sadagopan stepping in to defend his daughters as he confronts the consequences of his own earlier decisions. The confrontation becomes a turning point: father and son acknowledge their faults and the importance of honoring the daughters’ rights.
In the end, the entire family confronts the truth about gender equality and mutual respect. The men reconcile with the sisters, and the family celebrates the much-anticipated wedding of the fourth daughter, marking a hopeful, united future where daughters are recognized as equals and valued members of the family.
