The movie starts with Goutham (Jiiva) as a kid, being told that women are all bad and are very selfish by his father Sridhar (Nassar) because his wife had eloped that day. They then move to Chennai, where Goutham meets Baby (Santhanam) and Sri (Vinay). The trio becomes inseparable friends. 15 years later, it is shown that they are running an advertisement agency, and Goutham has stopped speaking to his father. After a heated incident at a friend's bachelor party, the three friends promise to never get married. They get an advertising offer from Sunny (T. M. Karthik), who sends Priya (Trisha) to assist them with the ad. Sonia (Andrea), an international model, is assigned to act for the ad. On the day of the shoot, Sonia falls in love with Goutham, and when the ad is finished, she bites his ear. Goutham retaliates by slapping her. Sunny scolds Goutham and tells him that he will never work with him again, but Priya supports Goutham, telling Sunny that it was Sonia's fault for behaving unprofessionally. After the shoot, Goutham calls up Priya and thanks her for supporting him. While speaking to Goutham, Priya meets with an accident. He rushes her to the hospital, where she recovers the next day.

After a few days, Baby and Sri decide to get married. When Goutham gets to know about it, he gets furious and ends their friendship. On the same day of the marriage, Sridhar tells Priya that he got married a second time many years before for his son's sake, and that is the reason for Goutham's anger towards him. He requests Priya to take care of Goutham. Goutham and Priya get another contract with Sunny and Sonia, and they leave for Switzerland for the shooting. On the day of the shooting, Sonia recalls everything Goutham had done and asks him to apologize for his act. He refuses because he knows that it is not his fault and then tells Sonia to leave. Afterwards, Priya takes the role of Sonia and acts for the advertisement. During the shooting, Priya and Goutham fall in love. When they come back from Switzerland, Goutham meets his friend and introduces Priya as just a stranger whom he met in the flight. Hurt by Goutham's cheap behavior, she leaves the airport. Goutham after returning home calls Priya and asks her to return his watch that he has given to her when they were in foreign. Hurt further, Priya reaches Goutham's office next day and returns his watch. Before leaving, Priya informs Goutham to contact Sunny in future, indicating that she doesn't want to interact with Goutham anymore. Later Sunny and Goutham discuss about the remaining work in the project and during the discussion Sunny informs that Priya is getting married to her friend working in US. Sunny further adds that he knows the feeling between Priya and Goutham and advises Goutham not to cheat himself. Goutham meets Priya at a beach and there quoting the airport incident, Priya tells Goutham that he is too egoistic that he will hurt anyone to maintain his macho image. She further tells him that due to his ego he has stopped talking to his father and friends who are very close to him and she can't afford to live with him since she knows that he will stop talking to her even if there is a small misunderstanding between them. After telling this, Priya leaves and Goutham starts feeling guilty.

When Goutham gets back home, he goes into his father's room and notices many paintings of him being happy, a wish that his father wanted. Goutham then discovers that his father was ill and rushes him to the hospital, where the doctors say that his father is suffering from pancreatic cancer and cannot be treated. Goutham becomes heartbroken. Sri comes to meet him and tells him that he knew that Sridhar was suffering from this disease. Baby then comes and says that Sridhar was the one who compelled them to get married so that Goutham might change his mind and get married. As the three friends reconcile, Priya comes to the hospital to meet Sridhar, where Gautham apologizes and admits to Priya that he has fallen for her. The film ends a happy ending with Gautham and Priya getting engaged in front of a recovering Sridhar at the hospital.
