Gokulan sees an attractive girl in his dream and is determined to find her. However, his father gets him engaged to another girl. Complications arise when he meets the woman of his dream soon after.

Actress Nagma was the first choice for Ramba charector. Later it was replaced by ramba due to call sheet issues. Again after few months Nagma was called to Devayani charector and also in other language movies too. But due to some diplomatic reasons Nagma quit from this evergreen movie.

Gokula Krishnan is a music-loving man who begins the film with a dream where he sees his dream girl. The only trademark he remembers from it is a mole which is situated next to her navel (belly button). He then becomes determined in looking for his "dream girl" with the help of his uncle and brothers-in-law. On the other hand, his father arranges his marriage to a village girl named Savithri, which Gokul (often referred to as "Mapillai") objects to, but Savithri loves him. Gokul later sees his dream girl, Swapna, at a wedding where he spots the mole on her navel. He then sings to her, impressing her, but she leaves abruptly. He later sees her at a music class which he teaches, and from then on, they love each other. Gokul tries to stop the marriage with Savithri in many failed attempts due to everyone in Savithri's family getting the wrong impression. Swapna then arrives at Savithri's village, and it is revealed that they are sisters. Neither of them knew that they love the same man.

Gokul tells Savithri's father that he does not want the marriage, which Swapna overhears. Knowing how much her sister loves him, Swapna is determined to get Gokul to forget her by faking that she has a blood clot in her heart. After much persuasion, Gokul agrees to marry Savithri. Throughout the film, another man, Vignesh, is in love with Swapna and tries to get her to marry him and if not, he will kill her with him also. When Vignesh reveals after almost killing Savithri that he loved Swapna but said that she will only love and marry Gokul, Savithri lets Swapna marry him.
