Set against the harsh and inhospitable terrain of Arunachal, Invictus is a first-hand account of survival against all odds. Tawang, an Indian military base at the Indo-China border, 10,000 feet above sea level, is abuzz. The Indian army division stationed there is scouring the mountains frantically. The Chinese army is on the lookout as well. Five Indian teenagers and a six-year-old girl, all army children have been missing since daybreak. With the arrival of monsoons, swollen streams are raging downwards into the Tawang Chu River. Surrounding mountains are filled with yaks, wild dogs, leeches, false vegetation and little else. Time is running out; if they are not found by 1700 hours, they will be presumed dead. Nidhie recounts that dramatic day which changed her and her friends forever and the survival skills from the jungle which shaped all her life choices ever since.
