While visiting her sick mother, Claire takes a wrong turn and stumbles into a dark passage of echoing doors and abandoned rooms. Lost, and attempting to find her way back, Claire encounters an over-protective dog and few denizens who are seemingly uninterested in Claire’s plight. Did they block the doors and windows to keep something out, or is a malevolent force stopping Claire from leaving? Why does the sun seemingly never rise? As panic sets in, time slips and begins to fall away.
