The film is set in New York City with intermittent flashbacks going back to Afghanistan, and not even one scene in India. The film is for those who love well made intelligent thrillers based on espionage. Kamal Haasan has made a film which has a touch of class.

The story begins in New York with Viswanath (Kamal Haasan) an effeminate Kathak dancer who has a marriage of convenience with his wife Nirupama (Pooja Kumar). Nirupama is a nuclear oncologist who is having an affair with her boss, a shady guy with terrorist links. The terrorist group is led by Omar (Rahul Bose), who has connection with terrorist in Afghanistan.

Meanwhile Nirupama realizes that her husband is not what he is and there is another side to him. Soon they are caught in a dangerous situation as Viswanath's past catches up. Here is superior quality cinema, a miniature masterpiece of how a terrorist evolves through training camps, the atrocities and how children are made human bombs and how America is fighting a losing battle in Afghanistan.
