There is the innocent Brahmin boy Satya (Navdeep), who comes from Nagercoil to Chennai to join an engineering college. Then, his problems begin when he encounters his father, the dreaded don Adhi Narayanan (Prakash Raj) and the latter's hot-blooded adopted son Kutty (Arya (actor)). Satya's girlfriend Sandhya (Sameksha) is accidentally wounded in a shootout between Adhi's gang and his rivals. Satya, on the prodding of ACP Thiagarajan (Adithya (actor)), is all set to identify Kutty as the culprit. Intimidated and threatened by the gang and in a state of confusion, Satya is shocked when Adhi suddenly changes track and makes friendly overtures to him, claiming kinship with him. With Kutty too going overboard with his brotherly overprotective attitude, Satya's life takes a comical and drastic turn.
