Young engineer Sam (Mischa Barton) is hired to oversee the demolition of a remote building. However, she learns that the architect, in a perversion of Egyptian mythology, buried people alive in the walls. As Sam works to unravel the mystery behind this awful place, she is haunted by the spirits of the victims -- and the discovery that she may be next to die. Cameron Bright and Deborah Kara Unger co-star in this eerie thriller.
