Plot
Chidambaram, a respected real estate broker from Azhagarkulam village, lives with his five daughters—Dhanalakshmi (Dhanam), Saroja (Saro), Leelavathi (Leela), Vijayalakshmi (Viji), and Bhavani. After the death of their mother, the girls are raised with the support of their maternal uncle, Bose. Chidambaram’s daughters deeply admire him, and he is well-regarded for his integrity within the village.
Initially, Chidambaram plans to marry Saro to Bose. However, when Manickam visits to see Dhanam, things change. Manickam, who was raised by his mother Rajam along with his siblings Selvam and Nirmala, is revealed to have had an affair with a married woman named Sarala. Eventually, the families agree to marry Manickam to Saro and Bose to Dhanam. The two couples marry—Dhanam remains in Azhagarkulam, while Saro moves to Chennai with Manickam.
On their wedding night, Manickam deceitfully visits Sarala. When her husband unexpectedly returns home, Manickam escapes in a hurry, accidentally leaving behind a ring gifted to him by his long-time mentor, Sivasamy. Sarala lies to her husband Ramachandran, claiming she gifted him the ring. Later, Sivasamy sees the ring and suspects something is wrong. He eventually discovers Manickam's affair and, disappointed, removes him from his business—leaving Manickam jobless. Rajam blames Saro’s horoscope for his downfall and begins to mistreat her.
Though Manickam loves Saro, he neither defends her nor allows anyone else to intervene. Only Selvam shows genuine concern for her. With the help of a hired astrologer, Selvam convinces Rajam and Manickam that Rajam’s life is in danger if she continues to live with her son. Believing this, Manickam and Saro move to a compound house, though he continues to visit Rajam often.
Meanwhile, Selvam and Leela fall in love. Manickam frequently clashes with Ramesh, Sivasamy’s son. Seeking revenge, Ramesh pretends to love Nirmala, only to humiliate her later. When Rajam and Manickam confront Sivasamy’s family, they are insulted. This ignites a long-standing feud between the two families.
Viji, the most impulsive and self-centered of the sisters, begins a relationship with Elango, a married man who hides the truth about his marital status. Ignoring Leela’s warnings, Viji falls for him and later marries him—only to discover his deceit. During a Diwali visit, Rajam insults Bose, prompting Dhanam to respond angrily. Rajam leaves the house with her family, abandoning Saro, who stays with her sisters in Azhagarkulam. The sisters eventually learn of Viji’s affair. After confronting Elango’s wife, Viji ends the relationship. Enraged, Elango tries to kill Viji, but she stabs him in self-defense. His wife clears Viji of any wrongdoing.
Viji then moves to Chennai to live with Saro. Selvam and Leela's relationship is discovered by Manickam and Saro, but Rajam disapproves and threatens suicide. Leela’s marriage is arranged with another man, but Rajam sabotages it by revealing Leela’s past. Eventually, Saro arranges her marriage to Ravi, a seemingly kind businessman. However, Leela later discovers that Ravi is mentally unstable, abusive, and was previously married to a woman named Sumathi.
Elsewhere, Gopikrishnan (Gopi), a garment factory worker, accidentally swaps bags with Saro and meets Viji while returning it. Mistaking Viji for Nirmala, he falls in love. After clearing the confusion and gaining support from Saro and Chidambaram, Gopi marries Viji. They move into a joint family house. Eventually, Gopi learns about Viji’s past when Elango tries to re-enter her life. Elango is later killed in a police encounter. Gopi consoles Viji and helps her move forward.
Meanwhile, Nirmala marries Santhosh, a man who disapproves of Rajam and Manickam’s behavior. Selvam, disheartened by Rajam’s manipulation, leaves the house and starts working under a man named Balu, eventually earning his trust.
Realizing her mistake, Rajam consults an astrologer, only to discover that she had been misled. She once again blames Saro. In a moment of rage, Manickam throws Saro out of the house during a heavy rainstorm. The next day, Chidambaram finds and brings her home. Meanwhile, Manickam vacates the compound house and moves back with his mother permanently.
Viji, struggling in her marriage, also returns to her father’s house. Leela, now pregnant, faces continued abuse from Ravi. He locks her up to prevent her from leaving. Ravi’s father eventually helps Leela return to Azhagarkulam. Saro gives birth to a son. Meanwhile, Manickam is brutally attacked by Ramesh over a family vendetta. At the same time, Bose is also hospitalized after being attacked by Ramesh. Both recover and return home.
Leela reveals the truth about Ravi’s abusive behavior and his previous marriage. Chidambaram’s family cuts ties with him. Ravi returns to take Leela back but fails. Facing pressure and guilt, Ravi begins blackmailing Leela.
Arundhathi, Balu’s daughter, is forced to marry Selvam, even though she loves a man named David. After discovering the truth, Arundhathi ends her marriage and reunites with David.
Santhosh, now jobless, returns from the U.S. Nirmala learns he misused her money. They argue, and he leaves, but later returns. Eventually, he betrays her by eloping with another woman, Julie. Nirmala is heartbroken. Sakthi, a humble woman who joins the office, begins developing feelings for Selvam.
Leela gives birth to twin girls, angering Ravi, who wanted a son. Viji gives birth to a son. Bose and Gopi start a business together, but it later creates a rift between them. The family relocates to Chennai. Bhavani begins her final year of schooling and catches the attention of Ramesh, who falls for her. Chidambaram arranges a spiritual trip to Devipattinam hoping for peace, but the trip is disrupted by an incident involving harassment and police intervention.
Gopi’s Kodaikanal trip is also ruined due to Rajam’s interference. Rajam and Nirmala leave Manickam’s house, and once again, Saro is blamed. Saro’s second pregnancy ends in miscarriage due to health complications.
Leela decides to become financially independent and starts working, despite Ravi injuring himself to stop her. Ramesh, after being rejected by Bhavani, becomes addicted to drugs and leaves home.
Six years later, Chidambaram and Bose have moved into a bigger house. Manickam, now an alcoholic, lives in a new home. Selvam remains unmarried. Nirmala has matured into a responsible working woman. Ravi still dislikes his daughters. Meanwhile, Viji, dissatisfied with her life in a joint family, begins creating rifts between Gopi and his relatives. She uses harsh and emotionally manipulative words to turn Gopi against them, hoping to break away and start a separate household, free from the influence and interference of his family.
Manickam hosts a housewarming event, during which Rajam insults Bose and Saro. An enraged Manickam physically assaults Saro, prompting her family to leave. Ravi also insults Chidambaram. Overwhelmed, and devastated further when Viji reveals her past, Chidambaram runs out of the house and is fatally struck by a lorry, dying in Gopi’s arms.
After his death, the family reconciles. Saro finally confronts Rajam and Manickam. The story ends on a hopeful note: Bhavani marries Murali, Selvam finds love with Sakthi, and Nirmala reconciles with Ramesh—marking a long-awaited moment of peace and redemption for the family.
