Don 2: The King Is Back is a 2011 Indian Hindi language action thriller film written, co-produced and directed by Farhan Akhtar.

Jointly produced by Excel Entertainment and Red Chillies Entertainment, the film stars Shah Rukh Khan, alongside Priyanka Chopra, Boman Irani, Lara Dutta, Om Puri, Nawab Shah, Ally Khan, Sahil Shroff and Kunal Kapoor.

The film received positive reviews from critics with praise for its story, cinematography, production design, music, action sequences and cast performances.

With a box office gross of over ₹202.81 crore (US$23 million), Don 2 became a commercial success and was the 3rd highest-grossing Hindi film of 2011.

Don gets cornered by his own associates, who reveal that they were offered a deal by the Europeans to have their cocaine from Asia open for sale in Europe.

Don returns to Malaysia and surrenders to Detective Malik and Roma, who have joined Interpol, where he is sentenced to death, sent to prison and soon meets his old rival Vardhaan.

In Zurich, Don meets his trusted companion Ayesha and they retrieve a tape from a secret locker whose key was under Vardhaan's possession.

Roma and Malik arrive in Berlin and unsuccessfully interrogate Diwan, while Don and his team execute a bank robbery.

However, Don blackmails Diwan into giving him German immunity in exchange for erasing the evidence of him being involved in James Warden's death.

Don negotiates with the Berlin Police and Interpol over surrendering the plates and a disc, which contains the details of the European underworld, in exchange for the safety of the hostages and defusing the bombs in the bank.

Following Vardhaan's arrest, Don obtains his immunity papers and surrenders the plates and the disc as agreed, while also getting Roma to an ambulance.
