Ranveer Singh (Saif Ali Khan), boyfriend of Sonia (Bipasha Basu), cons Vikram Thapar (Rajesh Khattar) so badly that he is divested of the five casinos that he owns in Istanbul. Ranveer?s next target is Armaan Malik (John Abraham), and he asks Robert D?costa alias RD (Anil Kapoor) and his comic assistant Cherry(Ameesha Patel) to introduce him to Armaan, promising him a commission from the profits he and Armaan would make in a fail-safe scheme he has in mind.
Ranveer charms Armaan as well as his step-sister, Elena (Deepika Padukone), who is a 50% partner with Armaan in all his profits. Soon, he establishes contact with Armaan Malik?s girlfriend, Omeesha (Jacqueline Fernandes), under the belief that she is the sister of Sonia. He tells Omeesha of his plan to destroy Armaan, like he had finished Vikram Thapar, as they both had been instrumental in killing his girlfriend and her sister, Sonia. On her part, Tania also pledges her support to Ranveer. It turns out that Armaan and Omeesha had conned Ranveer into believing that she was Sonia?s sister so that they could know what was in his mind.
Unaware of this, Ranveer agrees to steal the Shroud of Turin from the museum in Italy and sell it to Armaan at a discounted price. Armaan agrees to pay the hefty price with the intention of laying his hands on the shroud and manipulating matters in such a way that he?d also get his money back. Armaan strikes a deal with Godfather Anza (Aditya Pancholi), an underworld don, for the money to pay Ranveer.
Is Ranveer successful in stealing the shroud from the high-security museum? Does Armaan pay him the huge sum of money? Does Ranveer give him the coveted shroud of Turin? What is RD and Cherry?s role in this mission? Whose side is Elena on? Is Omeesha loyal to Armaan?
