At a time when Mumbai Police, headed by Police Commissioner (Nasser), announce that the much dreaded Mafia Raj is completely wiped out in the city, and there are no under world Bhai’s in Mumbai, a rookie named Surya (Mahesh Babu) lands in the country’s commercial capital with an intention to become a Mafia Don. His friend, Brahmaji receives him and brings him to Dharavi. He offers him shelter and tells him that he would soon fetch him a job so that he can settle down in life. But Surya wants to carve an identity for himself, by reorganizing Mumbai's Mafia Raj and eventually rule Mumbai. He then mocks as a cop and gets his first bounty and then he forms a gang of his own. Surya meets up with a local politician Laalu (Sayaji Shinde) who is in trouble and offers him help. Surya begins recruiting criminals and gangsters in Mumbai and starts to extort people for money. He slowly gains momentum and in the process becomes popular and feared among the people.
Meanwhile, he also knowingly tries to get romantically involved with Chitra (Kajal Agarwal), daughter of the police commissioner. In the process, he actually falls for the girl and tries for her acceptance. In the course of the film, Surya become popular among Dharavi's locals. He comes across as an extortionist, a baron, a philanthropist and an entrepreneur. His friendship with Laalu gets stronger and so does his political connections.

Surya reveals his plan to grow his network of organized crime all over India. He begins to set up branch offices for Surya Exports & Imports in all major cities, towns and villages all over India. He recruits local gangsters for staff and begins to forcefully collect two percent tax on every contract done in that area.
