Dorai (Arjun) is a do-gooder don, but a police force led by ACP Easwara Pandian (Prakash Raj) and his sidekick (Sathyan) are after him. However, the poor need him as he is a Good Samaritan running an orphanage. He has help from his friends Subramani (Manivannan) and Ayyanar (Vadivelu). Dorai has a problem: his mother (Sujatha) does not approve of his ways and feels that he is just a loutish goon. There is also a TV journalist named Anjali (Mallika Kapoor), who is in love with Dorai because of his daredevil ways. Dorai has a past: he was just an honest-to-goodness schoolteacher who ends up as the deathly Dorai after a fire ravages a school and kills several children. The incident forces him to take on the system of venal officials and politics. Now, Dorai's biggest task is to nip a dark and dire politician who wants to bomb the city.
