Gaurav Kapoor (Sidharth Malhotra), based in suburban Miami, plans to marry his colleague Kavya (Jacqueline Fernandez), who happens to be the woman of his dreams, but she prefers a man who is more adventurous and risk-loving. A Gentleman 2017 full
Running parallel to Gaurav’s life, is the story of clandestine spy Rishi Purohit (also Malhotra), who is seen to have been trying to extract some crucial substance from the Chinese Embassy in Bangkok. However, when a co-spy, Yakub (Darshan Kumaar), shoots down an innocent civilian, the dishonest move enrages Rishi. Nonetheless, he returns to Mumbai, where it is revealed that he works for Unit X, a spy organisation headed by Colonel Vijay Kumar Saxena (Suniel Shetty). Rishi explains to Col. Vijay that he can’t continue with such routines, and that he wants to start life afresh. Col. Vijay asks him to perform one last job for him, and this involves spying on a minister who Col. Vijay claims to be corrupt and wants to blackmail, and copying data from his cellphone into a hard drive which is wanted by Col. Vijay. Rishi does save contents into the hard drive, but Col. Vijay, having decided that Rishi is useless, instructs Yakub through a text message to kill him. Rishi senses the suspicion, and fights off Yakub and the other spies. Yakub manages to shoot Rishi, destroying the hard drive, but Rishi escapes.
Gaurav tries to hang out with Kavya on a date, and also meets her parents, who consider getting him married to Kavya. Meanwhile, he is ordered by his boss to visit Mumbai to close a business deal. Rewinding to Rishi’s life, he is shown meeting a man named Gaurav Kapoor, who works in a cyber firm in Miami, and has important data about the minister’s connections. When Gaurav is murdered by Yakub on account of being a liability, Rishi decides to adopt Gaurav’s identity to successfully escape from Yakub after his last mission. This leads to his present-day life in 2017 as Gaurav in a Miami software company, thus implying that Gaurav is in fact Rishi himself, and that the events leading up to his new life took place five years earlier in 2012.
