Helena is a doctor who should have retired a long time ago due to poor health, but she finds herself unable to leave her patients. Thirty years ago, she moved from Poland to India, where she has worked at the Jeevodaya centre for leprosy patients and their children ever since. To her youngest patients, she is not only a doctor, but also a motherly figure, and everyone at the centre calls her ‘mum’. There is only one person who seems to have a problem with her: the new Head of the institution. Unwilling to accept Helena’s authority among the patients, he has been trying to get rid of her. Despite being a Catholic priest, he does not appreciate her charitable work and has given her a derisive nickname, ‘Mother Teresa’.
