The Grieving Stones.

A small therapy group arrives at the Grief House hoping that a combination of solitude and shared effort will help them begin the healing process each of them so desperately needs. But their presence has awakened something in the old dwelling. Bound to the ancient standing stones on the nearby fields and a terrible crime, committed centuries before. The group will uncover the dark history buried beneath the stones and confront a transformation far more terrifying than they ever imagined.
