Peter and Julie, a young successful couple purchases a large run-down house, which they plan to renovate.
As they begin their restoration they discover that beneath the layers of wallpaper and paint their living room walls are mysteriously covered with plates. When they remove the iron plates, a strange sepia stain appears. As the stain grows it begins to resemble the shadow of a man climbing from the darkness beneath the house.
Each time they paint over it, it returns.
Sinister events in the house a century before have left an evil legacy that threatens Peter's sanity and the couple's marriage. Finally, their very lives are threatened by the historic horrors of their dream house.
