A waking nightmare pursues graduate student Hailey Maniates across San Francisco to Golden Gate Park where she is rescued by a towering homeless man. She seems able to read her rescuer's mind, but is it just a delusion? Doctors diagnose her as a paranoid schizophrenic and attempt to prescribe away her alleged hallucinations. But too many questions remain about Hailey and the man who saved her. He appears to suffer from the same mental condition and is convinced that some type of Gypsy vampire is trying to kill them both.
Against reason, Hailey finds herself more and more attracted to this strange man. Could he be a fantasy - or worse yet, a monster?
