The Blackwater Prison vanished decades ago—along with its inmates. Official reports claimed structural failure, but whispers of experiments gone wrong suggest something far worse. When investigator Jaxon Reed and his team are sent to locate a distress signal from the prison, they expect an abandoned ruin. Instead, they find something alive. The halls are haunted by prisoners who should have died long ago—twisted, hollow-eyed remnants of something unnatural. As the team fights to escape, they realize the true horror… the Forgotten Ones never left.
