`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. The conflicted Narasimha`s life gets more complicated when a confrontation with the group leader (Ashish Vidyarthi) turns his world upside down; now he`s caught in the middle of the law and the militants. The only way Narasimha can survive is when he finally takes matters into his own hands. Does he follow his conscience and thwart the movement? Or, does he look out for himself and his family, and embrace the Naxal cause?
