The film opens with the ageing gangster, Singaperumal, forcing himself on a young girl, Subbu. He is unable to perform, and vents his anger by slapping the helpless Subbu. Singaperumal is the grand don of crime in Madras. His lieutenant, Pasupathi, brings a proposal. A large stash of cocaine, worth about ₹ 2 crore, has entered the city. The guy bringing the stash wants to sell it for ₹ 50 lakh. Pasupathi sees the immediate easy profit, as well as the long term benefit (to control the cocaine market with such a large supply) and the recognition that they are able to pull off such a deal. The drawback is that the stash really belongs to their arch-rival Gajendran. Singaperumal knows that Gajendran is a vicious and unpredictable adversary, and the venture is risky and likely to become messy. He decides to pass. Pasupathi dourly suggests Singaperumal is getting old and rusty. He asks Singaperumal to loan him the ₹ 50 lakh so he can do the job himself. Pasupathi is prepared to face the risks, and in return for the loan, he offers Singaperumal a cut of the profits. Singaperumal agrees to the loan, but, instead asks Pasupathi to first get the stash and then think of the profit distribution. The money for the loan is brought to Singaperumal.

Life is a long, sunny adventure for Murugesan, who beats people up, sells his grandfather’s land, runs over rooftops, and incurs so much of his father’s wrath that he is prophesied to meet a horrible end. Not that this gloomy prospect affects him – he continues on his own sweet way until he runs into Parijatham (Poonam Bajwa), a demure, fair-complexioned, striking Iyer girl, the daughter of Panjami Iyer (Y.
