Allahabad stock trader Rizwan Ahmed arrives in Mumbai through a flight. He is determined to work with his hero, Gujarati financial maven Shakun Kothari (Saif Ali Khan). Rizwan bluffs his way into the city's largest trading firm and manages to convince them to give him a job. He ropes in a high-profile client and with the help of his co-worker and girlfriend Priya (Radhika Apte), he begins a successful career at the firm. When attending an event with Priya, he spots Shakun Kothari and gives stock advice that turns out to be correct. Kothari then hires him as his broker, warning that he can never lose him any money. After his first trade with Kothari's funds ends badly, Rizwan is desperate not to lose Kothari's account and illegally uses insider information from Priya to recoup Kothari's losses. Rizwan becomes close to Kothari and his wife Mandira (Chitrangda Singh), visiting Kothari's lavish home and relaxing on his yacht with Priya. Meanwhile, Kothari offers Rizwan a chance to make even more money when he learns that the government is going to begin accepting bids from telecommunications companies for a new project. Kothari informs Rizwan that he has bribed a government minister to select a company called Skycom and the two can make a killing on the deal. Kothari gives Rizwan the money to buy Skycom and Rizwan becomes the company's owner. He also convinces his new brother-in-law Anwar to invest all of his savings to Skycom shares. However, Skycom's bid is rejected, and Rizwan is ruined when Kothari sells off all of his Skycom shares right before the announcement of the bid winner. Rizwan discovers that Kothari deliberately set him up to take the fall for Skycom for Kothari's own personal monetary profit and that he arranged for Priya to influence him from the beginning. SEBI agents detain Rizwan for insider trading, but their real target is Kothari. Using information from Kothari's wife, Rizwan is able to prove that Kothari has been bribing government ministers wit
