Elizabeth Bennington is a shy young girl raised in privilege, living in the nearby town of Charlestown, just outside Boston. Despite her wealthy upbringing, Elizabeth was born with a congenital heart condition, which led to bullying at school and feelings of hopelessness. After a failed suicide attempt, which her parents intervened to prevent, she was sent to Bourneville Psychiatric Hospital. There, she underwent transformative therapy sessions that instilled in her a sense of hope and resilience, and she was released after a year.
However, Elizabeth harbors a secret: she can see into the future and is haunted by recurring nightmares that foreshadow unspeakable acts of murder involving a mysterious young man with raven-colored hair stained with blood. Her supernatural gift makes her both vulnerable and powerful.
Marty Bowles, who attends school with Elizabeth, is obsessed with her; and claims he loves her. However, his violent tendencies, including harming stray animals and practicing dark arts, pose a serious threat to her. Is Marty the dark-haired, blood-soaked man in her nightmares?
