Peter and Julie find their dream home: a terrace house in Sydney, run down but still mysteriously affordable. As they begin their renovations, the house reveals its secrets. The living-room wallpaper conceals iron plates attached to the walls, but when they remove these, a dark stain begins to grow on the wall: a stain that looks like a man climbing slowly up from beneath the house. They paint over it; it returns, every time. Will the events that took place in the house a century before cost Peter his sanity or both of them their lives?
