Terrified of the darkness of her dreams, Quinn does everything she can to stay awake, until the day when she dozes off in school and an amnesiac with psychic ability named Aaron enters her nightmare and the two are joined in fighting the darkness.
Quinn is a normal teenager, but for 23 days she has not slept for more than a few minutes at a time. Demons have invaded her dreams, stalking her and whispering of her death. The lack of sleep and crippling fear are ruining her life, and energy drinks and caffeine pills don't help. Then Quinn dozes off in the school hallway, and Aaron, an amnesiac with psychic ability, accidentally enters her nightmare. Aaron has a secret locked away in his memory that the demons are determined to keep him from discovering. Together, Quinn and Aaron can banish the darkness back to the underworld for good, but the demons will stop at nothing to drive the two apart.
