A young Seema discovers a cache of letters and papers in a locker belonging to her deceased mother. Besides chronicling her far-roving life across Canada, USA, Mexico, and India, these offer a glimpse into her private history-her feelings for M, a major leader of the Communist movement in British India and abroad; her commitment to, not only him, but also his cause; and her struggle to keep alive her feelings for him after his disenchantment with Communism. Even as Seema s mother grows increasingly cynical about the Communist cause, Seema blossoms into a rebel, voicing her dissent during the Emergency.
