It is the year 1999 and Karan Shergill (Hrithik Roshan) has been recently posted in the Siachen region of Kashmir, near the Indo-Pak border. As he bonds with his fellow officers and gets to know more about the region under their supervision, he reminisces about his previous life: how, as a good-for-nothing youngster, he had become a black sheep of their family, how he had took the entrance exam for Indian Military Academy purely out of a whim, how the harsh training had caused him to run away and return home, and how the decision had resulted into a breakup with his girlfriend Romila "Romi" Dutta (Preity Zinta) and how he had returned to the Academy, finished his training and emerged a winner. But there isn't much time left to dwell upon the past, as terrorists have crossed the Line Of Control and occupied a few key peaks to serve as attack points. The Indian Defense retaliates and thus begins Operation Vijay, a mission to reclaim the terrorist-captured points before it is too late. Karan is thrown amidst heated battle to capture an important peak, and he knows it very well that this might just be a great chance to serve his country and look the world in its face. Written by Soumitra
