After years of painstaking research at the cost of his domestic pleasure, Dr. Dipankar Roy discovers a vaccine for leprosy. The news is flashed over television and overnight, an insignificant junior doctor receives international recognition. Professional jealousy and abuse of power threaten Dr. Roy, even as the Secretary of Health reprimands him for breaking the news to the press. He is asked to report to the Director of Health. Professional colleagues Dr. Arijit Sen and Dr. Ramananda invite him to a lecture but it is merely a pretence to humiliate him. Dr. Roy suffers a mild heart attack but he refuses to go to the hospital. His wife and few others like Dr. Kundu stand by Dr. Roy, but the harassment continues; a letter from an American foundation is suppressed and Dr. Roy transferred to a remote village. The last straw is two American doctors receiving credit for discovering the same vaccine. Dr. Roy is shattered.
