Semi-dramatised documentary about the life of Mary MacKillop, an exceptionally single-minded and dedicated woman who became Sister Mary of the Cross in the Order of St. Joseph, Australia's first religious order.
In 1861, MacKillop, working in South Australia as a tutor, decided to dedicate herself to the education of the poor and devote herself to God. Unlike other orders, hers put itself outside the control of the local bishop, causing much resentment within segments of the Catholic faith.
