The story mainly revolves around Prakash, his wife Sathyapriya and his eldest sister-in-law Gayathri's conspiracies against their families to acquire Prakash's ancestral property Jai Hind Vilas.

Sathyapriya grows up in rich family in the village of Poongodi. Her parents Sundaram and Sampoornam were loving. She has two younger siblings, Dharani and Anjali. Sundharam arranges marriage for Sathya with Karthik, a businessman. Unfortunately, Karthik and Sathya's wedding is halted. Due to this, Sundharam dies of a heart attack. After her father's death, Sathya and her family moved to her uncle Devaraj's house in Chennai. There, Sathya and her family suffer much because of Devaraj's greedy wife Saroja. Saroja starts to take revenge on Sathya's family as Sundaram had rejected her son, Suresh's, marriage proposal with Sathya. Saroja determines to chase Sathya and her family from her house.

Then there is Jaihind Vilas family where Chidambaram is head of the family and proud fan of Mahatma. Chidambaram and his wife, Janaki, have four children. The elder Kumar is married to Gayathri, and they have a daughter Monisha. The second son Raju is lazy and sleeps at home all day. He has a wife Thilaga, who stays with her mother. They have their only daughter, and the youngest, Ragini, who goes to college. Their third son, Prakash, is short-tempered. Prakash's attempts to pass exams and get a government job are spoiled by Gayathri. Gayathri rules the family. The family is forced to do all the work for her except Prakash. Gayathri wants to take the Jai Hind Vilas property all for herself. Prakash is aware of this and obstructs her attempts to get the property. Gayathri, works as a GM in star hotel where Sathya joins to work to support her family.

Devaraj and Sampoornam want Sathya and Suresh to get married, but Saroja disapproves of it and arranges a marriage alliance with another girl. Meanwhile, Sathya gets introduced to Prakash's parents and Prakash himself. Her meeting with Prakash and subsequent sessions does not go well. Nevertheless, they become good friends, after Sathya saves Prakash even though he wanted to abuse her. Prakash protects Sathya's sister Dharani from some youths with evil intentions. This leads to him to fall for her innocence, and he decides to marry her. Dharani, who is in love with her cousin Suresh, does not like it. In the meantime, Prakash arranges house for Sathya's family after Saroja chases them out. Sathya meets Karthik and works at his office. Karthik's mother, Annapoorani realises her mistake for stopping Sathya's marriage to her son and decides to get Sathya married to Karthik, as Karthik still loves her.

On the wedding day of Prakash and Dharani, Gayathri provokes Dharani to elope with Suresh. When she does, Gayathri humiliates Prakash by saying that not even a single girl wants to marry him. Prakash gets angry and forces Sathya to marry him, to win over Gayathri. Sathya accepts as Sampoornam begs her. Thus, Sathya accepts what her mother Sampoornam says and marries Prakash. However, Prakash is happy to think that he has defeated his sister-in-law Gayathri in the challenge. Later, Prakash takes his wife Sathya with him to his house Jai Hind Vilas. At the temple, Suresh marries Dharani and brings her to Devaraj's home but Saroja chases them out.

Sathya, Sampoornam and Anjali disown Dharani. Devaraj accepts Suresh and Dharani. Saroja wants to separate Dharani from her son but Dharani outwits her. A further argument between Prakash and Suresh leads to a rocky relationship between the two families. Meanwhile, Sathya and Prakash understand and fall in love with each other. Prakash gets into a quarrel with Sathya's mother and prevents her from meeting her mother. Unable to go against Prakash, Sathya agrees. Sathya gets pregnant, and meanwhile, Saroja plans to separate Dharani from Suresh. She puts poison in her own drink and accuses Dharani of mixing it. Suresh chases Dharani from their house and she attempts suicide.

A lady saves Tharani from killing herself. But, she is revealed to be an evil woman who plans to sell Dharani. Prakash saves Dharani from the lady. Dharani does not understand them and stays adamant with them. Due to several things, Sathya has a miscarriage, and hides it from Prakash. No one knows the truth apart from Sathya's mother, sister and Prakash's sister-in-law, Thilaga. When Sampoornam accidentally blurts out the truth, Prakash is infuriated and chases Sathya out. He refuses to talk to her. When finally, after accepting fate, he changes his mind and goes to propose to her, but he is stabbed by some goons who messed with Sathya and Prakash in the past but survived. Sathya and Prakash start to care more for each other. Meanwhile, Suresh still suspects Dharani for poisoning his mother. Later, when the truth comes out, Devaraj and Suresh disown Saroja and chase her from their house. Suresh later accepts Dharani and her innocence.

Prakash and Sathya join the government and become officers besides the troubles given by Gayathri. Later, Prakash shows the true colors of Gayathri in front of Jai Hind Vilas family and then, Kumar beats and expels her from Jaihind Vilas. Now, Gayathri joins her hands with Nambi, a businessman who loves Gayathri. Gayathri again troubles Prakash and Jaihind Vilas with help of Nambi but Prakash and Sathya stand against her and manage her evil plans to save his property from her. Kumar then marries Akila, a widow, and has a son, while Gayathri creates many obstacles in their life but Prakash protects the family. Sathya becomes pregnant again. Gayathri was losing everything and was defeated by Prakash. Further, frustrated Gayathri kidnapped Nambi. Then, Sathya was arrested during pregnancy. Later, Prakash found all of Gayathri's evil acts and saved Nambi from her and had Sathya released, but Gayatri shot Nambi from a distance and escaped.

During the mean time, Gayathri is abscond and an IPS officer Mantra(look alike of Gayathri) is appointed to find Gayathri. Gayathri killed Mantra and went to her place to disguise as Mantra. Sathya and Prakash found Mantra is killed and applied the case in court. Court appoints a new officer ACP Samuel Raja to find the truth behind Mantra and Gayathri. After a few struggles, Gayathri is arrested, but escapes from police with a pistol and shoots Akila in front of Kumar and Prakash and kidnaps Moni. The next day she had kidnapped Maha and decides to kill her to win Prakash. Prakash and Sathya search for the two kids along with the ACP Samuel Raja. First they rescued Moni but While rescuing Maha, Prakash shoots Gayathri as a self-defense and sentenced to prison for six years. After that, Prakash and Sathya lived happily with their children in the Jaihind Vilas.
