Plot

A notorious thief allies with a street racer for a grand heist involving an elaborate game of deceit with authorities, who have their own dirty secrets.

Vibha Singh (Vibha Chibber) is a corrupt bureaucrat in the Accounts Department of the Government who pushes many of her clients into giving her "percentages" of their money which may either have been stolen or confiscated. With the support of her assistant Hamid (Pankaj Tripathi), she continues to do so and keeps hiding the money in a basement of the Rashtrapati Bhavan which is only known to her, and resumes her lifestyle until she receives news from Kirit Ojha, the Principal Secretary to the Prime Minister, that her help is needed critically by the Prime Minister for a certain task, and Ojha sends his man, Irfan (Boman Irani) to work with them and start an investigation from within their department to avoid being caught, as the investigation in question is against the notorious criminal King, who has recently stolen jewels from a jewelry house owner Mehta, and has claimed that his next target would be the Rashtrapati Bhavan. For the same, a hacker from the technical department, named Raj (Gaurav Chaudhari), is chosen to decipher messages of the gang.

Hamid and Irfan go on to investigate a street racing gang whose members have been striving hard to get close to King. The gang, composed of the leader, Tara (Jacqueline Fernandez) and her associates and friends Bikki (Vikramjeet Virk) and Naina (Sapna Pabbi), indulges in illegal street racing, and while Irfan speculates that a certain Arjun can infiltrate the gang and earn more information on King, a man appears out of nowhere. The man, Samar (Sushant Singh Rajput), disrupts Tara when she tries to meet a recent street race winner.

Samar races Bikki to impress Tara, but loses upon being caught by a policeman, Rathore (Bikramjeet Kanwarpal). As part of the bet, he lost the car and Rs 50 Lakhs. Samar wins Tara's trust by regaining the car given to him along with some money. Samar had bribed Rathore with the car for his release. He later calls Rathore and scares him by saying that the corruption squad is planning a raid at his house. Rathore panics and puts all his loot inside the car and parks it away from the house, which Samar steals.

Through the very course of events that follows suit, Samar bonds well with Tara, Bikki and Naina, holidaying with the group in Israel for the next few days, when Irfan realizes, along with Singh and Hamid, during that several messages that the gang have been receiving ostensibly as customer care offer messages are actually coded messages that the gang is using for internal communications. They ask Raj to decipher the rail code messages and discover that King's loot is located near the Gopigunj police station.

Tara receives the message and sets out with Bikki and Naina to retrieve it, with the police, headed by Irfan and Hamid, in hot pursuit, when it is revealed that the infiltrator, Arjun (Anuj Jain), was part of the street racing gatherings, and has been able to take the lead against the trio, but Tara, Bikki and Naina are then saved by a mysterious entity, who is then revealed to be Samar himself. Samar saves the trio from being arrested, but the gold is lost to Irfan in the process.

Admitting himself to be King, even as he used the name as a simple criminal alias to commit robberies (Samar says that he used the King's name so that the police searches for him, while he can operate freely), Samar gets the group going on the coveted Rashtrapati Bhavan robbery (Tara says that getting the gold arrested was part of the plan, so they could figure out where Vibha hides her loot inside the Rashtrapati Bhavan. The loot is rumored to be Rs 890 Crores), which is aimed to get them their hands on Singh's money, and their plan begins to work, but days later, much close to the heist, Irfan realizes that Raj was actually allied with King, and puts him to interrogation, hampering the hacking aspects of the group's plan.

On the eve of the heist, Samar relays to Tara that he will legitimately convert the stolen money to diamonds and store them in the Museum of London, and even as Bikki and Naina get married, Samar gets an alternate plan ready to be executed. The heist works perfectly well when Irfan, Hamid and Singh are put off their guard, with Singh being knocked unconscious and her money stolen, but during the mighty escape to the airport, Samar is made to suffer a diversion upward on the highway that causes him to be caught up in a dead end, which is when Tara reveals to him that she is King, and it was impulsive for her to betray him for all his smartness. Irfan and Hamid catch up with Samar and arrest him.

Two months later, Tara has a changed identity of a random Mrs. Khan, and goes to the Bank of London, with Bikki behind her, to store her diamonds in a vault. However, on the spot, she encounters Samar, who has also changed his identity as one Mr. Sharma, and she soon realizes that Irfan, who then appears before her, was actually Samar's boss, and that Samar was posing as Kirit Ohja to get Irfan introduced to Vibha. A shocked Tara, along with a helpless Bikki, then walks away with Samar and Irfan into the vault.
