Pachamuthu (Parthipan) by his own confession is a Porikki and due to the fear he is able to whip up, he rules over a slum area in Chennai. He is a sadist, a pervert and treats his own mother like a slave worker and swears at her. He is always on the look out to make a fast buck and has no qualms about doing dirty jobs for others; provided he is paid. One day he walks into a marriage pandal and is able to get a sneak view of the bride Poovu (Namitha) as she is dressing up for the marriage. Instantly Pacha takes a liking to her. He beats up the groom, marries the poor girl and takes her to bed after telling his shell-shocked mother and other women that he isn't going to wait until after they are married to have sex with her.
