The movie starts off with Sigamani (Bharath) as a young student refusing to go to school. His father, after having heated arguments with the school teacher, says his son does not have to go to school. Thus, Sigamani grows up illiterate and uneducated. After 25 years, he has grown up to be a siddha vaithiyar, following his family's roots. There is also a marriage broker in this story, Vijay Sethupathy (Singampuli), who tries hard to find an educated girl for Sigamani, but he is unable to. Due to the fact that Sigamani is uneducated, he is easily cheated by his friends. His only trustable friend is Paalpandi (Karunakaran). In desperation to marry an educated girl, Sigamani plans to wait outside a college to find a girl to love. He then sees Nandini (Nandita Swetha) and decides to go after her. One day, Sigamani and Paalpandi follow Nandini and end up in her house. After listening to an unknown phone call, Nandini's father Chinnadurai (Thambi Ramaiah) mistakes Sigamani to be a doctor who has studied MBBS and arranges for the marriage, which also takes place successfully and Sigamani is happy as his dream of marrying an educated girl has come true. Before the interval, Ravichandar places another major twist in the story to keep the audience in the edge of their seats.
