Overview: The story of Captain Balram Singh Mehta of India’s 45 Cavalry regiment who, along with his siblings, fought on the eastern front during the Indo-Pakistani war of 1971. Named after the Russian amphibious war tank “PT-76”, which floats on water like an empty ‘pippa’ (tin) of ghee, the film traces Mehta’s coming-of-age as he steps up to prove himself in a war to liberate Bangladesh.
