It is said that when one door closes, another one opens. In the Kingsley house, however, the doors close...a lot. Unfortunately, there are also doors that are opened. Especially after Tyson Kingsley finds an old journal that belonged to a voodoo priestess, Addie Lafrachet, from two hundred years ago. Through the entries, Tyson learns that the man who originally owned the home, John Dawson, was a disturbed man that enjoyed torturing and murdering others. The journal paints a horrific picture, including a rape that led to the birth of fraternal twins - one girl and one boy. John orders the death of the baby girl, not knowing about the baby boy. When the baby boy is left on a doorstep, bloodlines become confused and it is up to Tyson to unravel the mystery to find John and Addie's descendants and a box of ashes to finally set the spirits of Rain Hill Mansion free. With one mystery entangling another, Tyson, himself, could become trapped in the threshold between two worlds.
