In a remote village nestled in the Scottish highlands, a young woman named Fiona inherits her grandmother's ancestral home, a crumbling stone tower with a dark history. As she begins to renovate the tower, she uncovers hidden passages and ancient symbols that reveal a haunting truth: the tower is a conduit for a powerful spirit, trapped within its walls and yearning for release. Fiona must learn the secrets of her family's past and confront the spirit, before it claims her own soul.
