An IT manager named Akhilan (Arya) and a Tirunelveli girl named Anbarasi (Renuka Menon) are a newly married couple. They shift to their new house in Chennai and begin to live a happy life, even though their marriage was not love-based at first.

Soon, Anbarasi's family comes to visit them, and they leave Anbarasi's stepsister Kanmani (Akshaya), as she wants to pursue her post-graduate studies in multimedia. As Kanmani stays with Anbarasi and Akhilan in the same house, she begins to develop feelings for Akhilan, even though he is her brother-in-law. Kanmani continues to dream of romancing with Akhilan whenever Anbarasi is not around.

Akhilan does not want to hurt his beloved wife, who becomes pregnant and has given birth to their son. Tired of dodging Kanmani for almost a year, he seeks advice from a psychiatrist on how to solve his problem. The psychiatrist tells him to try and marry Kanmani off to anyone else. Akhilan secretly comes to Kanmani's village and requests Kanmani's male cousin to pursue and marry her. Following Akhilan's advice, Kanmani's cousin decides to marry Kanmani, but she rejects him constantly. After about a month, Kanmani's cousin kidnaps her, rapes her, and leaves her at Akhilan's apartment. This shocks everyone in the family, especially Akhilan. He admits secretly to Kanmani about his action and also told that the raping plan was not his advice. The whole family forces Kanmani to marry her cousin, because of the shame of rape being taboo. The marriage takes place, and Kanmani's family leaves to Thirunelveli.

The next morning, Kanmani commits suicide and dies. Akhilan, Anbarasi, and their child go back to Kanmani's village. Anbarasi's aunt hits Kanmani's husband as she thinks that it was because of him Kanmani died. Akhilan, standing right beside him, is all over guilty because it was he who planned all this to avoid Kanmani disturbing his married life. The film ends with the note “Good love, bad love, what is there in love?”[1]
