The film begins in 1857, when India was ruled by the British East India Company. Mangal Pandey is a sepoy, a soldier of Indian origin, in the army of the East India Company. Pandey is fighting in the Anglo-Afghan Wars and saves the life of his British commanding officer, William Gordon. Gordon is indebted to Pandey and a strong friendship develops between them, transcending both rank and race.

阿米尔·汗近日在庆祝54岁生日时，宣布他将主演一部印度版、印地语《阿甘正传》。
该片名叫《Laal Singh Chadda》，将由阿米尔·汗主演和参与制片，与他合作了《神秘巨星》的导演阿德瓦·香登执导，计划10月开拍，2020年印度上映。不是直接翻拍《阿甘正传》，而是改编，毕竟原版对应美国历史事件，而这部将对应印度历史。
