In a little known incident in the 1930s British occupied India, a handful of untrained teenage boys and girls, led by a school teacher, handed the British their first military defeat. Set against this backdrop, Chittagong is the story of the youngest and the most unlikely participant - a frail and diffident 14 old teenager, Jhunku Roy. It portrays an incredible journey of a teenager, who battles nagging self-doubts and reluctance on one hand, and a formidable enemy on the other, to achieve an impossible triumph.
