Horror Vault's take

When a maximum security prison becomes the site of a baffling series of inmate deaths, a detective is brought in to cut through the fear and find answers. The imposing walls that are meant to keep danger locked inside may also be trapping something far more malevolent. As the body count climbs, prisoners and investigators alike are forced to confront the possibility that not every threat can be seen or stopped. This gritty supernatural thriller uses its bleak institutional setting to amplify a mounting sense of dread.
