Kashmir is in turmoil because of terrorists trying to take over the land and the Indian army trying to find and eliminate them. Army commander Aman meets Adaa when posted to Kashmir to fight the insurgents. Adaa lives with her father, grandmother and a mute adopted sister. Adaa's brother Shakeel has joined hands with the terrorists to gain a free Kashmir. Circumstances soon lead to Aman and Adaa falling in love. Aman does not let the army know about his new relationship. He is given the task of finding and eliminating terrorists; he captures their leader, who happens to be Shakeel's mentor. Adaa's family learns about her affair with Aman. Her grandmother approves of the relationship, but her father requests Aman to stay away from them, as their love will not be approved in that place.

A disappointed Aman is then given another mission. Acting on a tip, he and his men go to raid a terrorist hideout but are attacked by the terrorists. Many insurgents are killed, and Aman and four comrades are taken captive by Shakeel. They demand the release of their leader from the government in exchange for the soldiers. But Adaa finds her brother's hideout, goes there, and pleads with him not to harm Aman. Using the opportunity, Aman breaks free and escapes with Adaa, just as the army besieges the place and rescues the captured army men.

Now Aman and Adaa's affair becomes known to the army. Suspicion falls on Aman that he is in cahoots with the terrorists, as he is not at their hideout, and he has run off with Adaa. As soon as he arrives in the city, he is arrested and court marshaled. Adaa does all she can to help Aman. She goes to the chief minister, who agrees to help her but on the condition that she deny any relationship with Aman in public, as it can affect the reputation of the army. Adaa does not agree to that. Instead, on the advice of her mute sister, writes a letter to the prime minister, telling him her story and seeking help for Aman. As fate would have it, she is called by a TV channel for a live interview and to tell her story to the world. This news spreads, and the terrorists are irked. They advise Shakeel to put an end to it all: He takes over a mosque, holding people hostage in exchange for their leader and Adaa's silence. They also bomb Adaa's house (at their leader's orders), injuring her grandmother gravely. Adaa decides to broadcast her story live, no matter what. Shakeel demands from the government that he negotiate with the man who had a relationship with his sister: Aman.

In the climax, Aman enters the mosque alone and faces Shakeel. Shakeel beats him black and blue, then sees that his father is one of the hostages in the mosque. At the same time, Adaa tells her story live on TV. Everyone listens to the heart-wrenching tale of the two lovers and a plea for Shakeel to return. Aman tells Shakeel that the terrorist leader had bombed Shakeel's house and his grandmother is in hospital. The terrorists then decide to leave, holding a man and a few hostages as guard. As soon as they step out, pre-planned by Aman who is wearing a bulletproof jacket, a sniper commando shoots him. He falls from the impact, thus giving the sniper a chance to aim at other terrorists. The army invades and forces the other terrorists to surrender. In the end, Adaa arrives and they leave the scene together.
