Major Ravi Mamman (Mammootty) arrests two LTTE terrorists in Bangalore, who are on a mission to assassinate the Indian prime minister on his visit to the city. On the run, he identifies the government minister K.K.Nair (Janardhanan (actor)) as the main conspirator behind the assassination plot. Nair anticipates a political coup after the death of the prime minister, through which he hopes to seize power. However, Mamman's attempts foil his ambition. Nair tries to buy out Mamman, who refuses his offers. In an attempt to save himself, Nair shoots Ravi Mamman, but the bullet accidentally hits Susan, Mamman's girlfriend, who dies on the spot. Nair fabricates a criminal case against Ravi Mamman, of killing Susan. Ravi is court-marshalled and sent to jail. Upon release, Ravi leaves to Dubai, where he emerges as a successful businessman in a short time. His business empire is spread all over the Middle-East. He is assisted by Chandran Nair (N. F. Varghese), an over-enthusiastic NRI. Ravi's sudden acquisition of power and influence makes him an enemy of many who are eagerly waiting for a chance to finish him off.
