Though Mookkaiya is having an illicit relationship with Hamsavalli, he looks down upon them and is irritated with Muthukalai's desire. During a jallikattu festival in the village, Veerannan fights with a bull belonging to Malaichamy and wins a gold chain as a prize. Upset with his bull being subdued by Veerannan, Malaichamy schemes to teach a lesson to Mookkaiya who constantly boasts about his bull. He manipulates Mookkaiya into announcing that the person who controls his bull will win Muthupechi as the prize. Muthukalai feeds Mookkaiya's bull medicinal herbs, resulting in Malaichami's man subduing the bull. Malaichamy demands that Mookkaiya get Muthupechi's man married to the winning man. When Mookkaiya returns home, his wife berates him, saying he has no right to declare his daughter as a prize. Mookkaiya, realising his mistake and the precarious situation he has created, commits suicide after killing his bull. Malaichamy does not relent; he approaches the Karisalpatti Panchayat and demands that Muthupechi should be married to his person. The Panchayat refuses and advises Malaichamy to forget the bet. When Malaichamy challenges the Panchayat and demands Muthupechi, the Panchayat makes necessary arrangements to get Muthupechi married to Veerannan by the next morning so that this issue will end. When Veerannan is returning after getting the necessary items, he is attacked by Malaichami's hoodlums. He fights and knocks out some of them. Fearing arrest, he runs away from the village and everyone assumes him to be dead. Unrelenting, Malaichamy comes with his villagers, camps at Karisalpatti and demands that Muthupechi be given to him. When the Panchayat refuses, a fight erupts between the two villages. The police intervene, bans the Panchayat and imposes restrictions on the movement of people in the villages. Enraged, Malaichamy closes the school run by him in Karisalpatti. However, the teachers plead with him and finally, run the school in the open. To pressurise the Karisalpatti villagers, Malaichamy orders his villagers to send back women who are natives of Karisalpatti, which leads to several women coming back to Karisalpatti.
