A faction feud in Tamil Nadu results in the death of Singaraayar's brother, and he, along with his two sons Dharma and Kaali, vow for revenge.

Time turns and comes to Chennai. Here lives Sakthi, an innocent and somewhat unlucky guy whose parents are no more and is ousted out of his job. His life takes a turn with a correspondence that he has five acres of land in his hometown in Tamil Nadu. He decides to sell that land and sets off to the village. In this process, he also meets Vaanathi, who is Singaraayar's daughter. However, much to Sakthi's bad luck, he happens to be the son of the man who killed Singaraayar's brother, and he ends up in their home itself. He takes advantage of a tradition of their house that not even one drop of blood should fall inside the house. Vaanathi falls for Sakthi in the meantime. He escapes in all the plans, much to Singaraayar's fury.

Soon the story takes a twist, when Vaanathi, not knowing that Shakthi is the son of the man who killed her father's brother, falls for Shakthi. Her cousin Raja learns of this and refuses to marry Vaanathi, though Shakthi had convinced him earlier in order to prolong Singaraayar's plan. Singaraayar had moved the engagement to the temple so that Sakthi cannot prolong the plan to kill him any longer. When Raja tells Singaraayar about Vaanathi's love, he slaps Raja, and in the engagement, Dharma carries a basket that he thinks Shakthi is hiding in, away from the temple to kill him.

It is then revealed that Shakthi is still in Singaraayar's mansion. He then runs away from the house, only to be chased by Singaraayar's men, but Shakthi narrowly escapes from his death and is saved by Vaanathi. When he crosses a bridge which is located at a high place, he refuses to let Vaanathi come with him, and now, Vaanathi discovers the truth and is heartbroken. Soon, Singaraayar and his men arrive to kill Shakthi, who somehow escapes. Suddenly, Vaanathi tells her father that she was the one who loved Shakthi. Shakthi has a change of heart and decides to go back to Singaraayar to express his feelings to Vaanathi. Singaraayar orders his men to beat Shakthi. First, an angry Dharma punches Shakthi, and that is followed by three blows. Shakthi then hits a rod and loses consciousness and his breath, bleeding badly, as well. Vaanathi cannot bear this and jumps into the river. Shakthi saves Vaanathi while the family had just watched in shock. Singaraayar and his sons are stunned and realize they must end the feud. In the end, Shakthi marries Vaanathi.
