After a particularly violent encounter with her husband, Derek, Madison wakes up to find him dead, having been killed in a manner strikingly similar to that of her visions. As a result, she becomes paralyzed with fear, contemplating the unsettling connection between her mind and the killings. Her trauma is deepened by inexplicable blackouts and the baffling onset of these premonitory episodes, which disrupt her sense of reality. While the police, including Detective Kekoa Shaw, are skeptical of her involvement, her adoptive sister Sydney strives to uncover the truth behind Madison's horrifying experiences.
