Dr. Tori Taylor rules the operating room with a cold precision that makes nurses cower and her colleagues take notes. But even with her success as a respected surgeon, Tori finds herself alone in her moment of desperation -- dying on her own operating table. Tori needs a heart transplant, but what she receives is far more than just a donor organ. Lying loveless and friendless in the recovery room, Tori experiences flashes of terrifying events she never witnessed. Soon she leaves her controlled world and starts investigating a homicide only she believes happened. Is she hallucinating? Or will someone believe her in time to stop a murderer from killing again?
