Ghost Stories for Christmas - Season 0 Episode 9 Stigma

A family moves into a cottage in the countryside. The cottage is situated near an ancient megalithic stone circle, and one of the stones which the family arrange to have moved is in the garden of the cottage. However, as two workmen attempt to lift a large, heavy stone from their garden, an ancient curse is unleashed which causes the mother to bleed uncontrollably, despite having no wounds. Once the stone is finally moved, a skeleton is found buried there. The implication is that the mother's body is re-enacting the ritual execution of a witch who was buried under the stone centuries earlier.
