In September 1957, Philomena Borloff, along with her two children, Anastasia and Silas, disappeared from Borloff Manor without a trace and were never seen or heard from again. Citizens of Castleton, Kentucky, believed her husband, Josef, murdered his family and disposed of their bodies; however, after an investigation into their disappearance produced no evidence of wrongdoing against Josef, he was never charged with a crime and continued to live alone in the home until his death 60 years later.

When Joan Buchanan, newcomer to Castleton, purchases and moves into the house four years after Borloff's death with her two children, Pietra and Chandler, and their border collie, Conroy, she is unaware of the bleak rumors or dark history associated with it.

It doesn't take her long, however, to realize that something mysterious is taking place inside her new home. Missing and misplaced personal belongings, insect and rodent infestations, mysterious noises coming from the basement, and prophetic and hallucinogenic dreams are only the beginning of the horrors about to befall the Buchanan family.

Residing in what is rumored to be the most egregiously haunted house in the state of Kentucky, they're about to learn the true meaning of evil and torment.
