Sami Srinivasan (Srikanth), a Brahmin boy, and his friend Karunakaran (Vishnu) grow up in the Royapuram slums and attend the same school. Karuna is a rough and tough boy, but Sami is a bit naive. They are close buddies. Once, they see their class teacher Roja (Pooja Umashanker), being brutally murdered before their eyes by a gangster. Dejected at local police not taking any action, Karuna kills the gangster but gets caught by the cops. Sami tells the police that Karuna committed the murder. However, both are bailed out of trouble, enmity brews between them. As years roll, hatred increases. Also, as fate would have it, a twist occurs: the two characters switch roles. Sami, who was naïve as a kid, turns into a rowdy and becomes the right hand of local gangster Narayanan (Thiagarajan) when he becomes an adult. In contrast, Karuna, who was very violent and brutal in his childhood, turns out into an honest and brave police officer who gets posted in his same locality. Sami is still against Karuna. Trouble erupts when Sami loves Karuna's sister Malar (Poorna). In the meantime, Shruthi (Poonam Bajwa) loves Karuna. What happens between the two forms for the rest of the film.
