In this new biography, students will follow Agnes Gonxha Bojaxhiu from her humble Albanian birth to worldwide celebrity as Mother Teresa. The nun who attended to the dying and diseased in Calcutta, India, and established her Missionaries of Charity around the world is revealed to have a singular determination from a young age. As a woman in the patriarchal Catholic system, she had to prove to the hierarchy, even the Vatican, that she was capable of handling each project she proposed. Her vision to live and work among the "poorest of the poor" as one of them led to the founding of a new order that tended to society's outcasts.

The doctor tells Teresa he wants to find a medicine which will stop people getting river blindness, but he behaves strangely and Teresa feels she cannot trust him. What is really happening?
