The film adapts the E.O. Chirovici novel, The Book of Mirrors. Its protagonist is former homicide detective Roy Freeman, who in the wake of a cutting-edge Alzheimer’s treatment, is tasked with re-examining a brutal murder case from his past — the grisly murder of a college professor. Intrigued and fighting to regain his memory, Roy enlists his former partner to help him revive the investigation. This time though, things unfold very differently when they encounter a magnetic and mysterious woman: as he uncovers a tangled web of contradictions and secrets, Roy is forced to face a horrific reality that changes his world forever in the blink of an eye.
