It's been nearly a year since volatile detective Ben Carson was suspended from the NYPD for fatally shooting another undercover officer, an accident that not only cost him his job, but fueled the alcoholism and anger that has alienated his wife and kids and left him crashing on his sister's couch in Queens. Desperate to pull his life together, Carson takes a job as a night watchman at the burned-out ruins of the Mayflower department store, which was destroyed by a massive fire that devoured numerous innocent lives. As Carson patrols the eerie, charred remains of the store, he begins to notice something sinister about the ornate mirrors that adorn the Mayflower walls. Reflected in the gigantic shimmering glass are horrific images that stun Carson. Beyond projecting gruesome images of the past, the mirrors appear to be manipulating reality as well. When Carson sees his own reflection being tortured, he suffers the physical effects of his fractured visions. His sympathetic but skeptical sister Angela dismisses these bizarre "nightmares" as a consequence of his stress and guilt over the accidental shooting, but Carson's estranged wife Amy, a no-nonsense NYPD medical 2 examiner, is less forgiving. Her husband's increasingly erratic behavior frightens her, pushing his family farther away--and, she fears, it's putting their children in danger. As Carson investigates the mysterious disappearance of a Mayflower security guard and its possible connection to his ghastly visions, he realizes that a malevolent, otherworldly force is using reflections as a gateway to terrorize him and his family. Carson must somehow uncover the truth behind the mirrors--and convince Amy to help him battle the greatest evil he has ever faced.
