Red Alert: The War Within is based on the true story of Narasimha (Suniel Shetty), a poor farm labourer who desperately needs money to fund the education of his children. To earn his way, he finds himself in the midst of the Naxalite movement, forced to make difficult, and morally questionable, choices. At first, he starts as a mere cook for the terrorist group. Before too long, he graduates to weapons training, shootouts and kidnappings. A good, kind man trying to earn for his family, Narasimha finds himself in a position he had never bargained for. Does he follow his conscience and thwart the movement? Or, does he look out for himself and his family, and embrace the Naxal cause?
