Line of Control (LOC) is the story of the Kargil War of 1999, more specifically the individual stories of a few of the soldiers who fought and died for their country. The Line of control is basically the borderline between India and Pakistan and both nations have posts on either side monitoring and defending the borders. The film starts of with several of the Indian posts being captured what at first seems by certain militant groups but later on the army learns that the Pakistan army is either involved in the capture or backing it because of the artillery with which the enemy is attacking. Several battalions are sent off to take care of the situation. But these soldiers face an incredibly challenging and dangerous task since they have no idea how the enemy is positioned or how many of them there are. In addition, the hilly terrain is harsh. The soldiers have to attack uphill while the enemy has the advantage of surveying the Indian soldiers from a height therefore knowing exactly how many and how strong they are.
With such a challenge facing them, the Indian army soldiers face an almost impossible war that they MUST win in order to protect the borders of Kashmir and the country. There are three main battalions: the Gorkhas, 18 Grenadiers, 13 Jakrif. And each is assigned to capture a vital post. The film tries to tell the true stories of many of the soldiers who fought and died doing their duty.
