Anchoress is a 1993 British drama film directed by Chris Newby.
The screenplay is partly based on accounts of an historical female anchorite, Christine Carpenter, who was walled into her anchorhold in a village church in Shere, Surrey, in southern England, in 1329. The story revolves around the girl’s mystical visions of the Virgin Mary, the local reeve who wants to marry her, and the priest who walls her into his village church and his dislike of her mother, a midwife whom he regards as a witch. https://en.wikipedia.org/wiki/Anchoress_(film)
