One morning in his house, Saravanan receives his ex-girlfriend Meera’s wedding invitation. He and his friend Paarthasarathy aka Paartha leave for Pondicherry to attend the wedding via car. En route, Saravanan recollects his past: He was a ruthless youth working in a film theatre with Paartha. He lives with his parents; his father, Varadharajan, who is educated and works as a college professor and his mother, Shenbagam, who is uneducated and is trying to pass an exam, just to get her college degree. One day in traffic, he sees Meera, a girl training to be an air hostess and falls for her on site. He follows her to a cloth shop and also to her Air Hostess class. He saw her house and he and Partha go to her house, as Meera calls them. There, Meera threatens Saravanan by showing her father’s photo, who is a Deputy Commissioner of Police (DCP), Mahendra Kumar. But still, Saravanan follows her and asks her to love him. Meera takes him to Mahendra Kumar’s office and he asks Saravanan to stop following Meera. Meera tells Saravanan that she has some qualifications required by her lover like shaving regularly, dressing well, breaking his friendship with Paartha, coming on time, etc. Saravanan tells this to Partha and Partha asks him if he or Meera is best for him. Saravanan tells him Meera is more important to him than Paartha, causing a break between Saravanan’s and Paartha’s friendship.
Later, Saravanan joins Paartha’s broken love and asks him to rejoin his love. Partha agrees and then they go to Mumbai, following Meera in a flight. There, Meera alas tells him that she loves Saravanan. After some months, Meera calls Saravanan once, but he does not pick up the phone and tells Paartha that Meera is not his real love and it is all nothing, but a drama. But, he really said that for fun. But, Paartha had accidentally switched on the phone while Saravanan told him all this.
