Critics and audiences have shared mixed but largely patriotic sentiments about the film:

Set against the backdrop of the 1962 war in Arunachal Pradesh, the film follows Jaswant Singh Rawat as he chooses to stay behind at the after his platoon is ordered to retreat. Armed with limited ammunition and aided by two local girls, Sela and Noora, Rawat remarkably held off the Chinese army for 72 hours . He managed to neutralize over 300 enemy soldiers before his death, earning him the Maha Vir Chakra . Critical Review
