Plot

Rocket Raja (Karthi) is a small-time thief who steals anything he comes across. In the company of his partner, Kaatupoochi (Santhanam), he enjoys life to its fullest and even falls for the charm of the beautiful Swetha (Tamannaah). However, his life changes forever when a young girl named Divya Rathnavel ends up in his care; he looks exactly like her father Rathnavel Pandian IPS (Karthi). As Raja discovers the girl's past, it is revealed that Rathnavel Pandian is an honest policeman who is a nightmare to criminals, but that one gang of criminals in the village of Devipattinam are intent on killing him and his daughter. Rathnavel Pandian's colleagues put Divya in Rocket Raja's care so that the criminals could not track her, and also because Rathnavel Pandian is on the verge of death following a gunshot to his head. Despite this, Rathnavel Pandian is intent on fighting back. Unfortunately, he dies following a long battle with several criminals who had been chasing Raja and Divya. Upon seeing his courage, Rocket Raja (with the help of Rathnavel Pandian’s colleagues) steps into Rathnavel Pandian's shoes and finishes his unfinished work. He also takes on the responsibility of taking care of Divya, with the help of Swetha.
