Dhoom 2
In the Namib Desert. Mr. A skydives onto a train that is carrying the Queen Elizabeth II, where he steals her crown by disguising himself as the Queen, beats her guards easily, and escapes. ACP Jai Dixit and the newly promoted SI Ali Akbar Khan are introduced to Shonali Bose, a special officer assigned to investigate Mr. A's case, who also happens to be Jai's former classmate. After the initial investigation, Jai analyses the underlying trend in Mr. A's heists and concludes that the theft will follow in one of two famous Mumbai city museums. When Jai realizes that the artifact in the museum he is guarding happens to be imperfect, he rushes to the other museum, where a disguised Mr. A steals a rare diamond and escapes.
