This patriotic drama begins with Major Rajendran (Suresh Krishna) being killed by the Pakistani terrorists in the Indo-Pak border just as the war between India and Pakistan begins. Pakistani Army led by General Jaffer Khan (Mukesh Rishi) sends a battalion to capture a village on the Indian side of the Line of Control.
