Seenu (Santhanam) is a happy-go-lucky guy. His parents Ekambaram (Aadukalam Naren) and Bhavani (Pragathi) search for a bride to get him married within three months as per an astrologer's advice. Seenu does not believe in arranged marriages and tries to woo girls around him. Eventually, he falls in love with Maha (Ashna Zaveri), but she does not reciprocate. Meanwhile, Seenu's wedding is fixed with Akhila (Akhila Kishore) by his parents. Seenu finds out that Maha also loves him and decides to cancel his wedding with Akhila with the help of his maternal uncle Ulaganathan (Thambi Ramiah). One day, Seenu calls Akhila to inform her about his love for Maha. Coincidentally, it was Akhila's birthday, and he prefers not to disappoint her. Maha spots Seenu with Akhila and understands the truth. She also informs this to Akhila. Maha breaks up with Seenu. Akhila forgives Seenu and prefers the wedding to proceed as planned. On the day of the wedding, Seenu gets a call from Maha, asking him to marry her in a register office or else she would commit suicide. Seenu rushes to the register office to save Maha but gets shocked seeing her wedding with her cousin. Seenu understands that it was a prank played by Maha to revenge him. Seenu rushes back to his wedding hall to marry Akhila, but Akhila married her family friend as everyone believed that Seenu eloped with Maha. Seenu's parents worry thinking about his situation, but Ulaganathan gets his daughter (Vidyullekha Raman) married to Seenu.
