Aadhi asks Dheena and his henchmen to cut the hands of the MLA and his men especially the right hand and Dheena completes his task.Meanwhile Dheena falls in love with a girl named Chitra(Laila) who initially mistakes him to be a bus conductor and later a vegetable seller. One day one of Dheena's henchmen ('Mahanathi' Shankar) spots Chitra and her cousin in the plaza and reports to Dheena. Dheena pretends to meet her by chance and pays their bill using the plaza manager's money. One day Chitra calls Dheena's home landline number posing as 'Pepsi' Uma and comes to know about Dheena's tricks. Meanwhile Dheena comes to know that someone (Shyam Ganesh) has teased his sister Shanthi and thrashes him. One day when Dheena meets Chitra they are ridiculed by a gang of rowdies but Dheena stays calm as he thinks that girls hate people who are violent.

As a coincidence the rowdies come and Dheena thrashes them and informs Chitra that he is a local goon. Later she comes to know that Dheena has love for her as she did. Meanwhile the same person who teased Shanthi gave a love letter to her and Dheena beats him up and comes to know that the persons sister was Chitra.
