Gaurav (Sidharth Malhotra) lives in Miami and works in a big company. He has just recently bought a lovely house as he wants to settle down in life by marrying girlfriend Kavya (Jacqueline Fernandez) and having several children. But Kavya, though fond of him, doesn’t find him marriage material as he is too safe and not at all adventurous.

Rishi (Sidharth Malhotra) lives in Bombay and works for the National Security Council’s (NSC) Unit X. Colonel (Sunil Shetty) is in charge of Unit X and he misuses his position to amass wealth for himself in the form of kickbacks and through other illegal means. He uses Rishi, Yaqub (Darshan Kumar) and several other youngsters who work for him, to further his personal gains rather than to work for the country. Rishi is tired of working in a dangerous job and wants to call it quits as he wants to settle down in life with a wife and children. However, Colonel won’t allow Rishi to quit so easily. He gives him one last task – to get the hard disc of a computer which one Gaurav Kapoor (Kunal Sharma) from Miami is to deliver to defence secretary Mishra (Chittranjan Tripathy). The hard disc contains incriminating evidence against Colonel and hence he wants it anyhow.

Rishi obliges and manages to get hold of the hard disc but the disc gets damaged when Yaqub shoots at Rishi with a view to kill him as per Colonel’s orders. Rishi doesn’t die but disappears with the damaged hard disc.

As the drama progresses, the lives of Gaurav and Rishi intersect at one point as Gaurav comes to Mumbai for an assignment but is mistaken as Rishi by everyone around him. Soon, trouble follows him to Miami where the agents of Unit X come hunting for him. It is then revealed that Gaurav is, in fact, Rishi, who mends his way of living to lead a normal life.
