ONE NIGHT. NO WAY OUT. Trapped inside the locked-down facility, Marcus and Elena must navigate through madness, betrayal, and an army of shadows. Friends become enemies, and trust becomes a deadly weapon. As the body count rises, they discover that the killer isn't just hunting them... he is cleansing the hospital. One name at a time. Can they survive until sunrise, or will they become the next names on THE LIST? A terrifying psychological thriller that will make you afraid of the dark... and of anyone wearing a white coat.
