Arjun (Mahesh Babu) and his twin sister Meenakshi (Keerthi Reddy) finish college, and their parents decide to look for a good man to marry Meenakshi. Meenakshi shows Arjun a letter from their friend Uday (Raja Abel), who confesses his love for her and asks her to elope with him as his parents Bala Nayagar (Prakash Raj) and Andal (Saritha) are arranging his marriage with a different girl. Meenakshi tells Arjun that she too is interested in Uday. Arjun goes to Madurai, where Uday lives with his parents and is about to get married. Arjun tells Uday's parents about the letter and asks their consent for marriage. Uday dares to marry Meenakshi before their parents' approval comes. Uday's parents agree for Meenakshi as their daughter-in-law, though they have different plans in mind. Meanwhile, Arjun meets Roopa (Shriya Saran), who also happens to be from Madurai, and they fall for each other. In Meenakshi's house, Uday's parents plan to kill her as they had lost a chance to grab a millionaire's property by the arranged marriage. They make multiple attempts to kill Meenakshi, but she survives. Arjun comes to the conclusion that they are trying to kill his sister, but Uday and Meenakshi do not believe him. At last, Meenakshi believes him when they try to kill her while Uday was away. She escapes with Arjun's help and gives birth to twins. In that fight, Bala dies and Andal becomes paralytic. Uday watches how they tried to kill Meenakshi and believes Arjun's version. They all reconcile and live peacefully.
