Karen, a desperate young mother struggling to make ends meet, takes a night shift janitorial job at a massive furniture factory. She’s assured that she’ll be the only one working during these late hours. However, when she notices a suspicious vehicle parked in the lot, running but unmanned, and discovers a factory door left slightly open, an unsettling feeling creeps in. The more she explores the dimly lit, empty halls, the more she begins to question whether she truly is alone. As strange occurrences escalate and a growing sense of danger surrounds her, Karen must navigate the eerie isolation of the factory to uncover the truth—and survive whatever lurks in the shadows.
