Death Certificate revolves around the life of a tribal woman Sabitri and her search for her husband Ramlokhon who happily provided water to thirsty rail passengers in a remote corner in Eastern India.
Ramlokhon doesn’t return home one evening. Ramlokhon’s friend Shibu comes to look for him in his village and informs Sabitri and the grand old man (dadu) in the village that Ramlokhon is missing.
They embark on a journey to look for Ramlokhon through the mountains and forests filled with memories of the missing man. They arrive at the station only to hear that someone has been run over by Kiul passenger train. Station Master informs Sabitri that he hopes it isn’t Ramlokhon but in the worst case scenario in case the dead body is his she must obtain a death certificate.
