Anu (Madhu Sapre), Shiela (Padma Lakshmi) and Rina (Katrina Kaif) are three supermodels who live together and enjoy a luxurious life. One day, a fashion show, in which they are participating, goes horribly wrong where these women have a fight with co-models, resulting in the theft of diamonds by Paparazzi and other audience. These diamonds were actually supposed to be smuggled to the middle east, but the delivery got botched up due to these supermodels, although unwittingly. This makes the girls unwantingly enter the world of crime and underworld, ruled by Bade Miyan (Amitabh Bachchan), Medium (Gulshan Grover) and Chhote (Jackie Shroff). The girls are ordered to execute the Biggest Bank robbery ever and make up for the losses they have caused. The dons think girls have all beauty and no brains. This makes the girls make a plan against these Dons itself. They use their charms to fool the Dons and try to pull the wool over their eyes. Will the girls succeed in doing so? Or will the hierarchical Dons realise their hidden motives?
