Kaali (karthi) is a regular middle class guy in north Madras and he is quite short tempered. He has a close friend Anbu (kalaiarasan) who is into politics. They have constant clashes with a group led by Maari (vinod). Meanwhile, Kaali falls in love with Kalaiarasi (catherine) and she also falls for him. Story takes a turn with a wall being erected and both sides determined to have the painting of their leader on it. What happens from there forms the rest.
