Sridhar (Ajith Kumar) is from a middle-class family headed by his father (K. Vishwanath). Shiva (Raghuvaran) is Sridhar's elder brother and the breadwinner for the family, consisting of his wife Shantha (Sithara) and sister (Preitha Raghav). Sridhar, upon completion of his graduation, aspires to become a music director and tries hard to secure a chance in movies, but all his efforts go in vain. Sridhar's search for a chance continues for eight years. Despite that, his family members support him very well and encourage him whenever he feels dejected.
Sridhar meets and befriends Viji Chandrasekhar (Jyothika). Viji also likes Sridhar and his aspiration. Slowly, love blossoms between them. Viji gets introduced to Sridhar's family, and they too like her. However, Sridhar has plans of marrying her only after getting his first break in music. Viji also understands Sridhar and supports him. A CD shop owner (Manivannan) is Sridhar's neighbor, and he also encourages him. Sridhar gets an opportunity to compose music for a film. He feels extremely happy and goes for recording. Unfortunately on the same day, the producer meets with an accident, and as he feels it as an inauspicious sign, the movie is dropped.
Viji's younger sister Sudha (Soumya) gets a good marriage alliance, but the groom's family finds it odd upon seeing Viji being unmarried. Viji's father (Jaiganesh) requests Sridhar and Viji to get married so that it does not stop his younger daughter's wedding proposal. Viji's father asks Sridhar to leave away his dream of becoming a music director as he has been already trying hard for years. He also offers him a job so that he can marry Viji.
However, Sridhar refuses to let go his dream. He is ready to sacrifice his love for the sake of his ambition. He requests Viji to marry someone else as he cannot give up his passion for music. One day, Shiva has a heart attack and is admitted to the hospital. The doctors say that Shiva has heart problems and needs rest. Sridhar is shocked to see his brother's condition. As Shiva was the only income earner in the family, now Shantha and Preitha decide to take up some jobs to help earn money for the family.
Sridhar worries seeing that, though he also feels proud about the love and affection shown by his family members towards him, as no one asked him to forego his ambition and take up some job despite this condition. However, Sridhar decides to go for a job so he could ease his family's financial burden. He informs this and leaves for an interview, giving up his ambition. After a few years, it is shown that Sridhar secures a chance to compose music becoming a leading music composer and marries Viji.
