Calcutta, My Love returns to the Calcutta of the 1960s and 70s and to the birth of the radical Naxalite movement when a section of the Communist Party of India (Marxist) led by Charu Majumdar and Kanu Sanyal led a violent uprising in 1967. The film's protagonist, a young rural boy from a modest family who goes to Calcutta for further studies, gets unwittingly sucked into the movement even though violence is not in his character. His life whirls around his love for a girl, his commitment to the movement and his imprisonment. Calcutta, My Love is a chronicle of those turbulent years as seen through the story of the young Animesh.
