About the title
The protagonist, a young woman named Alison, regains consciousness to find herself locked in a dark basement full of corpses. Having no idea where she is, the girl quickly realizes the killer is still nearby. To survive, she decides to play dead — and becomes a witness to monstrous events. Day by day, Alison uncovers more details of what's happening: the basement turns out to be part of an isolated house where brutal rituals and experiments are carried out on victims. New captives occasionally appear in the locked space, and the girl must decide whether to keep hiding or take action, risking exposure.
