After staying too late for a high school project, a boy is forced to run home in the pouring rain. He happens upon an old house and stops to rest, only to find himself trapped. Feeling a gaze on his back and with no other option, he must explore the dark and decrepit building to find his way out. Unfortunately, the only way forward is deeper inside, and the house may not be as small, or as empty, as it first seems...

Who is the house's master? Where are they now? Does the house contain allies or enemies? Understanding the nature of the building may be crucial for the boy to see the light of day again.
