Molly, Lizzie (two sisters), and their mom, Rachel, move from downtown Detroit to Ferndale, Michigan, into a very old house. After many strange things begin to happen, Rachel does some research on the house's history and finds out that the house was owned in the 1950s by a 17-year-old Germans girl, Greta, and her abusive husband, and that while she lived there, she went missing and was never seen again. Upon searching the house, Rachel and her brother discover the girl's skeleton boarded up inside the wall of Lizzie's bedroom with scratch marks on the wood inside, suggesting she was locked in there while still alive. They assume that by releasing her remains, she can move on in peace to the spirit realm. However, after being locked up for so long and deprived of her life, Greta isn't so compliant.
