All Luke Simone wanted was a fresh start. After a tragic accident on the job, he longed for escape, for somewhere far enough to find peace. The prison guard position in rural Utah seemed like the ideal get-away—a new home, new job, and best of all, he could escape his past. His task is simple: guard the bottom floor at night, a singular hallway with white doors, all except one. Cell 900. Rusty red, its occupant—unknown. But as the days pass, Luke’s uneasy comfort is shattered. A strange series of break-ins at his cabin, puzzling disappearances, and unexplainable murders, send Luke into a frantic search for the truth—before he winds up a victim himself. Is the real nightmare lurking behind the door of the mysterious cell, or are there other sinister forces at play?
