Child custody of their daughter Sona, who was in Shanthi's sister's house when the breakup occurred, is given to the mother by the court. One day, Suriya takes Sona to a fair and somehow loses her. In the confusion that follows, Sona falls from a Ferris wheel and is taken to the hospital by Vijay. She is brought to Raghu's house once she recovers. Soon, Vijay discovers that Sona has lost her hearing in the accident. Some days later, Suriya finds that Sona is missing. Suriya finds Vijay, and the two get into a huge punch fight. Then, Raghu tells everyone that Sona is in his sister's house. Since Sona's custody is given to the mother, this action of Raghu's is wrong in the eyes of law.
