The house on Park Corner may appear normal to those looking in, but those inside know it is anything but. The residents are unsure of how they ended up there, and they soon discover that any attempt to leave results in them ending up right back where they started. Moreover, there are consequences for trying to escape. New arrivals come and go, while some appear to have been trapped there for decades. Some disappear for days, weeks, or even years, only to suddenly reappear as if they had never been gone. There is a profound darkness that seems to reside within the tenants of this house, manifesting in terrifying ways.
