The story starts in the city of Mumbai, where a motorbike gang (a gang of robbers on hi-tech motorbikes, led by charismatic Kabir, is sweeping through Mumbai, outwitting the police at every turn) starts breaking into banks and other public places and vanishes onto the Western Express Highway.
Assistant Commissioner of Police Jai Dixit (Abhishek Bachchan), a no-nonsense cop, is called onto the case. Dixit seeks the help of a local bike dealer/racer named Ali Akbar Fateh Khan (Uday Chopra) and devises a trap to catch the gang, but it fails. Kabir (John Abraham), the leader of the gang, eventually taunts Dixit, claiming that Dixit can’t catch him even if he is right in front of him. He is proven correct, and Dixit’s failure apparently causes him to part ways with Ali.
