Siri (Trisha) is a traditional, simple, rural girl from Andhra Pradesh who is brought up by her only older brother Sivaramakrishna (Srihari). Twenty years prior, their rich father from a nearby town married another woman and kicked the rest of Siri's family, humiliating them on the way. Their mother dies leaving toddler Siri in the care of 13-year-old Sivaramakrishna. With help of relatives, her grave is built on the small land which the siblings inherited, but the Zamindar Muddu Krishnaiah tells them that it is his land, since their mother had not repaid a loan from the man. Sivaramakrishna begs Muddu Krishnaiah and asks for an extension promising to work day and night to pay off the loan, as long as they don't tear down his mother's grave. Muddu Krishnaiah agrees upon security from the local station master. Slowly, Sivaramakrishna turns the tables using his handwork and becomes a rich enough farmer, and Siri grows up to complete engineering in a nearby town. One day, Lalitha, Siri's best friend from school time comes to their house to invite Siri to their house as she is getting married. Sivaramakrishna agrees to send Siri a week ahead of the marriage. Santosh(Siddharth), Lalitha's cousin, a rich city boy born to millionaire parents Janaki and Prakash and brought up in London, also arrives on the same day with his mother.
Slowly, Santosh and Siri fall in love, but Janaki does not bear it as Siri is a poor girl, and thus does not meet their standards. Santosh is also to be married to Janaki's brother Srinivasa Rao's business partner's (JP) daughter’s Dolly. When Sivaramakrishna arrives at the wedding, Janaki humiliates him as well as Siri. Both are thrown of the house after Janaki accuses them of trying to entice and trap Santosh. When Santosh learns of this, he goes to Siri's house and pleads to her brother to accept him. Sivaramakrishna gives him a chance, just like he was given a chance by Krishnaiah when he was a child. Santosh is tasked to take care of the cows, clean up after them, and grow more crops than Sivaramakrishna by the end of the season; if he does not, Santosh shall leave the village forever and never see Siri again. Krishnaiah is not happy as he wanted his son to marry Siri. With them, Dolly, and her father trying to get Santosh to lose the competition, Santosh has to work hard for his love, eating red chillies and rice every day, even though he can't bear it. In spite of many antics from Krishnaiah's and Dolly's side, Santosh eventually proves his love for Siri to Sivaramakrishna and succeeds in growing more grain. However, Krishnaiah and JP kidnap Siri and then try to force her to marry his son. A fight takes place in which Santosh kills Krishnaiah‘s son while Sivaramakrishna violently defeats Santosh's uncle's business partner and Krishnaiah. After realizing that Santosh and Siri should be together, Sivaramakrishna takes the blame for the murder and spends five years in prison.
Sivaramakrishna is released from prison after five years and Janaki accepts Siri as her daughter-in-law. Finally Siri and Santosh get married, in everyone's presence.
