The story revolves around Chinna (Suriya), a kindhearted village youth with a hunchback and is lauded for selfless service to others. He covers up his disability with humor and optimism. Unmindful of his looks, Chinna goes around looking for a suitable bride with the help of his friend Kuzhandhaisamy (Vivek), a marriage assembler. Brushing aside many insults hurled at him, he carries on with his life.

In contrast is Karthik (also Surya), a violent college student who madly loves his classmate Priya (Jyothika). She meets Chinna, who assures her that he would get her married to the man of her dreams. Priya and Karthik plan to elope with Chinna's help as her father rejects Karthik. However, she is killed in a frac by Varadhan (Bobby), a gangster, as revenge against Priya's father DCP Nair (Devan), who arrested and asaulted him. She dies in Karthik's arms with Nair watching and he arrests him thinking he's responsible for Priya's murder. Chinna saw Varadhan killing Priya, but Varadhan tells that he will be killed if he tells anyone what he saw. After Karthik is jailed as Priya's killer, Chinna pleads Nair and tells the truth behind Priya's murder. Meanwhile, Chinna comes across an orphaned, poor, blind girl Shenbagam (Jyothika). He wins over her heart by helping her out when her brother (Thalaivasal Vijay) died.

After his efforts, she gains her vision (Priya's eyes are transplanted to her). This results in a tussle between Chinna and Karthik as to whom Shenbagam now belongs. However, fearing his looks, Chinna decides to give way to Karthik and ends up staying in a temple where Kuzhandhaisamy finds him and brings him to Shenbagam. Shenbagam does not care of looks and accepts him. Before their marriage, Varadhan returns to avenge Chinna. Karthik remembers Priya and avenges her death by brutally killing Varadhan. Karthik approves Chinna and Shenbagam's wedding before being sent to jail. The film ends with the couple spending their honeymoon in Ooty.
