In a valley of astonishing beauty, a small family lives in an idyllic setting – a father, mother and young son. They are the very picture of happiness and love. But appearances can be deceptive. This pastoral landscape is the strife-torn valley of Kashmir, and the son Altaaf, is an orphan of war who has been adopted by a policeman, Inayat Khan and his wife Neelima. Altaaf is slowly recovering from the psychic wounds of seeing his parents and younger sister shot to death before his very eyes by a masked man. One day, Altaaf discovers that the man he now calls “Abba” is the same masked intruder who killed his defenceless family during a firefight with militants. In that single moment of discovery, a warrior is born. Altaaf puts on the same mask that Inayat wore that night and flees into the darkness. Ten years later, a famed guerrilla fighter named Hilal Kohistaani leads a band of determined men into the Kashmir valley. These men are unknown and unsupported renegades, very keen to earn a worldwide reputation in a single stroke. The group has planned just such a mission, Mission Kashmir, which will change the map of the subcontinent forever. Hilal is willing to sacrifice anything to successfully accomplish Mission Kashmir but, in order to do so, Hilal needs a fighter whose deadly combat skills and burning anger will drive him to the target, like a missile. Hilal Kohistaani believes that he has such a man, Altaaf. And so, Altaaf returns to the streets and bylanes of his childhood. He fights for Hilal but is also obsessed with his own private mission: to kill the masked intruder who haunts his nightmares – Inayat Khan. In Srinagar, Altaaf also meets with his childhood sweetheart Sufi, in whose beauty, compassion and optimism, Altaaf finds hope and love. As the countdown to Mission Kashmir ticks relentlessly nearer, Altaaf and Inayat engage in a duel to the death. The fate of Kashmir will depend on the outcome of their final, ferocious encounter.
