High school junior Violet uses her uncanny ability to sense murderers and their victims to try to stop a serial killer who is terrorizing her town, and although her best friend and would-be boyfriend Jay promises to keep her safe, she becomes a target.

Violet, having only told her family and boyfriend that she can sense dead bodies and agreed to join forensic psychologist Sara Priest's team of eclectic investigators after Sara learned about her ability, works on a case involving the murder of a college girl by a serial killer dubbed "the girlfriend collector" and runs the risk of becoming his next victim.
