The police are baffled by a master thief known only as Mr. A (Hrithik Roshan) because he leaves an ’A’ symbol after each robbery. Mr. A steals the crown jewels of a queen by sky diving onto the train carrying them, and then disguising himself as the queen and as usual escapes the authorities.
Meanwhile Ali (Uday Chopra) who is now an officer fouls up a mission and is narrowly saved by ACP Jai Dixit (Abhishek Bachchan). They soon meet ACP Shonali Bose (Bipasha Basu), who has been assigned to solve the case of Mr. A. Shonali and Jai are ex-classmates. Their apparent flirting makes Jai’s wife Sweety (Rimi Sen) jealous. Jai realises that Mr. A is actually challenging everyone to catch him. His next theft will be in Mumbai.
There are two places where he might strike, A jewelery shop, and a museum. Jai and Shonali stake out the jeweler while Ali stakes out the museum. Jai realises that Mr. A will rob the museum after learning that the supposed target of Mr. A is damaged. Mr. A manages to make his escape by roller-blading and using a magnetic device. Shonali is disheartened that Mr. A escaped and decides to resign. Mr. A is planning to leave the city, but at the airport he learns that someone else, using his name has announced that he will rob the sword kept in the Junagadh fort. Mr. A decides to meet the imposter. The imposter turns out to be Sunehri (Aishwarya Rai), who confesses that she is a fan of Mr. A and would like to be his partner. Mr. A is doubtful at first, but later he agrees. But Sunehri is actually working for Jai Dixit.
Mr. A takes Sunehri to Rio de Janeiro to train her and also for their next heist. Jai and Ali follow them to Rio, where they meet Shonali’s twin sister Monali (Bipasha Basu). Monali takes a liking to Ali. Mr. A finds out that Sunehri is working against him. After he confronts her, Sunehri decides to stop betraying him and work with him. Their robbery is successful.
There follows a high-speed bike chase, ending with Mr. A and Jai fighting on a waterfall. Ali manages to capture Sunehri, to stop Mr. A. Sunehri shoots Mr. A, just as he wanted, so that he is not arrested by the police. Jai lets Sunehri go free, deeming it punishment for her to live alone. Six months later, Sunehri and Mr. A are shown running a restaurant in the Fiji Islands, but Jai follows Sunehri and finds Mr. A. Mr. A gives Jai information on where to find the money from the previous heists. Jai later lets Mr. A and Sunehri go free as Mr. A gives him the information to all the stolen goods, and also Mr. A is dead to the world and there is no point in catching a thief who’s already dead. But he warns Aryan(Mr.A’s real name) that if Mr.A ever returns, then he will catch him. Jai receives a phone call from Ali, and tells Ali to return to India, as they’ve got a new case
I dint like da movie. The stunts are good but illogic, could have been faster after the interval, but its really slow and boring.
