Commando Officer Dharma has been implicated in a valley bridge bomb blast case by a group of terrorists who had fourteen years earlier implicated Karma in a murder case. Dharma's younger brother Rakesh and Karma's lost son Pradeep are working as architects for a company which is trying its best to grab the tender of Asia's biggest shopping centre in competition to another company N.I.S.
But just before the tender date Menka is murdered and Rakesh is arrested on murder charge. Dharma and Karma become bitter enemies to save their brother and lost son respectively, but later on their enmity - turns into an unbreakable friendship. During their course of action, Dharma-Karma come to know that the owners of N.I.S. were earlier associated with terrorist activities. This begins a cat and mouse game to apprehend N.I.S. and to find the real murderer of Menka.
