Radhakrishnan (Dhanush) alias Rocky is a 10th grade dropout youngster who is looked down upon by his father (Pratap Pothen), because of his sharp contrast to the rest of the family, all educated and well placed people. Rocky spends most of his time in a mechanic shop with his group of friends (Mayilsami, Nellai Siva and others). 'Padikathavan and 10th failed' as his father refers to him, doubles up as a petty goon when his family members are in trouble. Meanwhile, one of his relatives is nearly married. One of his friends suggest that he falls in love with a highly educated girl, so earnestly he looks around by hovering around women's colleges. So he makes himself fall in love with Gayathri (Tamaannah) a rich girl who after a few misunderstandings falls for him. In turn, he starts to honestly love her.But, at first, things doesn't work out the way Rocky planned! Meanwhile there are some goons after her, as her father is Samarasinga Reddy (Suman) a deadly don in Andhra. Our hero saves her from her dad's rival (Sayaji Shinde) and follows to her home in Hyderabad, where he realizes that another Tirunelveli goon Kasi Anandan (Atul Kulkarni), the one he accidentally killed in a flashback, has put a price on his head. Rocky goes and settles the matter by fighting and winning against Atul Kulkarni.
