Billiant medical student Zack Degen’s world is shaken when he discovers the hauntingly beautiful drowning victim, Harper James. Although the authorities officially label her death a suicide, Zack encounters reason to believe that Harper James was murdered. Compelling evidence of the murder presents itself in the form of an alluring young woman, Rachel, who claims to be channeling Harper. Incredibly, Rachel seems to know facts that only the victim would know. A soon-to-be physician, Zack adheres to science and rational thinking, rejecting the notion that Rachel could actually be channeling Harper, but soon Zack’s reason-based metaphysical view is torn apart as Rachel’s other-worldly and sometimes horrifying visions lead Zack and Rachel on a race to find - and then to escape - a sadistic killer.
