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.

The movie revolves around three old men. Ashok Lalwani alias Lali, (Anupam Kher) is not happy with his wife (Rati Agnihotri), who is a staunch believer of God and doesn’t spend time with him.

The three men plan a holiday to Mauritius to have some fun, where they meet Ahana (Lisa Haydon), who is a social networking addict and gets annoyed because her rival girls have more Facebook likes and her ex-boyfriend had been commenting and liking their posts and condemning her at the same time.
