The film tells the story of Chandrama Singh (Bobby Deol), who was raised by Baba (Danny Denzongpa), a Naxal leader based in the southern interiors of Bihar, after his family was brutally murdered. He later gets picked up under a covert Governmental program jointly conceived by RAW and Intelligence Bureau to carry out political assassinations. He falls in love with Shubhi (Priyanka Chopra), a kindergarten teacher, and decides to lead a reformed life but a chanced encounter entangles him in the world of crime once again.

Kabeer Kaushik, the director of the film had approached Bobby Deol to play the lead role in his debut film, Sehar, which was eventually played by Arshad Warsi. Despite liking the script Deol turned it down because he was not prepared to work with a debutant director and also felt that the plot was similar to some other film. Filming for the movie began in October 2007.^{[citation needed]} The song "Gola Gola" from the film picturised on the festival of Holi was released exclusively on radio stations on 21 March 2008, to coincide with the festival of Holi. Rosa Catalano features in a dance number in the film titled Trance.^[4]
