 After the 1970 India-Pakistan war, which gave birth to Bangla Desh, and the defeat and unconditional surrender of the Pakistani army, some 30 odd Indian soldiers were not released by the Pakistanis. In 2003, some 33 years after the war, tensions continue between the two countries, and both are at the verge of war. Indian politicians and army personnel are aware of the prisoners, but are unable to take any action, as doing so may jeopardize their lives. Human Rights groups are kept in the dark, and the prisoners are transferred to other locations, when the news of any such group gets to the prisons. When proof of his dad, Ranvir Kaul (Amitabh Bachchan) reaches Gaurang (Akshaye Khanna), he decides to travel to Pakistan to try and free his dad. Unkown to him, his dad has already tried to escape some 17 to 18 times, only to be captured, and brutally beaten by his captors. Gaurang is told that going to Pakistan is easy as entering a mouse-trap. Once you are in, you cannot get out, no matter how hard you try.
