Vinu Ramachandran is a young executive working in
Dubai. He is engaged to Anjali and forms a close acquaintance with her brother, Anandan, who works as a plant manager at a factory in
Jamshedpur. It has been five years since Vinu's breakup with his ex-girlfriend, Parvathy but he still hasn't been able to move on. Anandan coaches Vinu in overcoming his feelings of betrayal. However, Anandan is also not leading a perfectly happy life, as he is temporarily separated from his wife who is also named Parvathy, after an anonymous letter slandering her had arrived to Anandan. Vinu, who now considers Anandan as the brother he never had, takes it upon himself to ensure happiness in Anandan's life and helps him reunite with Parvathy. However, things go haywire when Vinu and Anandan meet in-person for the first time as it turns out that the Parvathy in both of their lives is the same person. Initially, Vinu tries to stop the wedding due to the awkward situation with the help of his friends, his brother and his colleague Kunjunni. However, Kunjunni backs out since Anandan is his friend from school, and he doesn't want to get involved. Later Vinu, after talking with Anjali, realizes their happiness is what matters, and decides to proceed with the wedding. Meanwhile, Anandan learns that Vinu's ex-girlfriend is his own wife. Thinking that the love letter sent to Parvathy was sent by Vinu, he immediately sets out to stop the wedding. Kunjunni meanwhile decides to help Vinu and tries to ruin the wedding, but an angry Vinu slaps him, leading to Kunjunni joining Anandan's side to try to stop the wedding. Anandan tries to stop the wedding with the help of his uncles, who turns out are in a direct fight with Anandan's father Sudevan and have their own agenda to create problems. Meanwhile, Vinu's old friend turned enemy, Saravanan, whose marriage he had ruined unintentionally, as well as a stalker, George, who used to follow Anjali, try to stop the wedding by themselves. Finally, on the day of the wedding, Anandan gets closure after talking with Parvathy and her father as well as his own parents and realises that they had known about Parvathy and Vinu long ago, but they hid the truth from him, to protect him. He also realises that the anonymous love letter sent to Parvathy was sent by his own uncles to create a rift in the family. After learning the truth and realising his mistake, Anandan trashes up Saravanan, George and Kunjunni as well as his uncles and their goons and proceeds to prevent any disruption to the wedding. Finally, Vinu marries Anjali amidst all the chaos and makes peace with Parvathy. The story ends happily with Vinu and Anjali, as well as Anandan and Parvathy, happy together. ==Cast==
