The world's oldest desert in Namibia... A solitary railway line... A royal family on a royal journey... From the sky, like lightning... a FLASH! The centuries old Royal Crown is stolen!
Ali's (Uday Chopra) dream of becoming a police officer has come true. He is now ACP Jai Dixit's (Abhishek Bachchan) 'right hand man'. Together, they are trying to keep a tight leash on the crime in India. Little do they know what they are going to be up against.
Aryan - Mr. A (Hrithik Roshan) - A hi-tech international thief. After pulling off a series of impossible heists all over the world, his next target is Mumbai, India. The case is given to Jai and Ali. Helping them put the pieces of the puzzle together is ACP Shonali Bose (Bipasha Basu), Jai's college mate, now a police officer in her own right. For the last two years Shonali has been tracking these amazing thefts and is now an expert on this thief, who no one has seen.
Once in Mumbai, Aryan finds his match in Sunehri (Aishwarya Rai), a petty yet clever thief. She makes him an offer he finds very hard to refuse. A partnership! Aryan accepts.
And so the game begins - a game of cat and mouse.
From the desert of Namibia to the backwaters of Goa, the mean streets of Mumbai and the ancient forts of Rajasthan, and finally to wild and exotic Rio De Janeiro.
Does Jai Dixit manage to nab Aryan? OR does he prove to be too much for him?
