Ludmila is a European woman of mysterious origins who has come to India to tend to the poor and the sick, she is not an actual nun; her title of "sister" being conferred upon her by the Indians she helps. As a result, the Catholic and Anglican communities view her mission with some suspicion. Ludmila has independent sources of funding, and operates a free clinic, and sanctuary for the sick and dying. She is assisted in her work by Mr. DeSouza.
