A young family move into a rural Georgia home situated on the old Underground Railroad, and they experience true terror when the ghosts of the past refuse to rest in peace. Andy (Chad Michael Murray) and his wife Lisa (Abigail Spencer) thought they had found the perfect place to raise their young daughter Heidi. But almost immediately after settling into their quaint, historic home, Heidi experiences a series of troubling supernatural encounters. Later, when Lisa's easygoing sister Joyce (Katee Sackhoff) shows up for a visit, the restless spirits inhabiting the house begin to make their presence known.
