After finding a 14-year-old girl wandering alone at 5 a.m., police try to track down where she came from, only to discover the “friend” she was visiting is a grown man hiding something even more disturbing inside his basement.

A single discovery leads detectives into a case where nothing is what it seems, and the truth gets harder to deny by the minute.

Some woke up to screaming. Others never saw it coming. In a confined space with no way out, a routine trip turns into a desperate fight to survive as chaos erupts aisle by aisle.
