Somewhere near Vairengte in the north-eastern state of Mizoram, the sun is harsher than it should be in April. Suddenly, a helicopter appears on the horizon and soldiers slither down the rope that is dropped from the chopper as it hovers over a field where the crop has been recently harvested. The men disappear behind a hillock and then there's silence. Minutes later, gun shots are heard. Amidst the heavy firing, the soldiers, who literally appeared from thin air, throw a grenade into one of the structures. The grenade explodes and the soldiers return with a captive man. Another man tries to escape but he is shot by a sniper who takes aim from behind a set of trees.
