Radhakrishnan a.k.a. Rocky (Dhanush) is a 24 years old 10th grade dropout youth, who is looked down upon by his father Ramakrishnan (Pratap Pothan) because of his sharp contrast to the rest of the family, who are well-qualified in education. Rocky spends most of his time in a mechanic shop with his friends. Rocky's friends advise him to love and marry a well-educated girl so his name will be added with her name after marriage (i.e. indirectly he gets a degree after his name). He looks around by hovering around women's colleges to find a perfect girl for his mission. He succeeds in his attempt and makes Gayathri (Tamannaah), a well-educated rich girl, fall in love with him. He starts to love her and takes her to a shopping mall where she is confronted by a group of rogues who work for Rami Reddy (Sayaji Shinde), a rival of her father Samarasimha Reddy (Suman), a notorious don in Andhra Pradesh who protects his daughter by destroying the gang and taking her back to Andhra from Tamil Nadu. Rocky goes to thug-for-hire Assault Arumugam (Vivek) to help him marry Gayathri. Rocky saves Gayathri from Rami and follows her home, where he realizes that another Thirunelveli rowdy named Kasi Anandan (Atul Kulkarni), whose brother (Sashikumar Subramani) he accidentally kills, has put a price on his head. Kasi declares that if Rocky wins him in hand-to-hand combat, he will never be disturbed by him. Rocky accepts his deal and smashes him down. The movie ends as Rocky walks out while his gang applauds for him.
