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.

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.

The groom admits to his mistake and reunites with his old girlfriend. Saravanan and Paartha walk off the marriage hall, just then Meera comes and hugs Saravanan, hence reuniting with him.

Shakti (Madhavan) is a young man from a village with no job but much ambition and dreams. As he sees his life pass him by, stuck in a rut in his hometown, he decides that he will try his fortunes elsewhere. Chennai beckons him and off goes Shakti to join his uncle Kirikalam (Vadivelu), who has a stall of magic tricks at an exhibition. Kirikalam is not really a magician, but is posing as one, and his amateurish tricks don’t exactly bring in big crowds.
Next door to Shakti and Kirikalam’s stall though, is one ever-populated with visitors. The reason: it’s an all-girls stand, with mermaid costumes as the theme. Velli (Reema Sen) is the ‘head mermaid’ at this stall run by her sister, and bitter quarrels between her and Shakti ensue, when he feels that she and her team are unfairly taking their customers away, and she has this impression of him being an unsavory character. This misunderstanding is seen at different occasions where Velli and Shakti just happen to be in the wrong place at the wrong time — be it when Shakti gets off the bus from his village, asks for directions and is told to follow Velli, walking in the distance (Velli thinks he’s a womaniser) or when Shakti finally catches up with a miscreant who had picked his pocket and demands his money back — only Velli walks into the scene only at the demanding part. This whole collage of scenes is animated, with Kirikalam and Shakti trying to woo customers back to their stall, Shakti and Velli getting into arguments, and a general state of “fun” ruckus. Of course, love has been brewing as an undercurrent between the two young people.
