Dr. Alex Delaware first meets actress Zelda Chase when called upon to evaluate her five-year-old son. Years later Alex is reunited with Zelda when she is involuntarily committed. But tragedy strikes and shortly after her release Zelda is discovered dead in the grounds of a palatial L.A. estate. Having experienced more than enough of the city's dark side to recognise the scent of evil Alex turns to his friend LAPD Lieutenant Milo Sturgis for help in finding the perpetrator. Meanwhile Alex is caught up in another quest: the search for Zelda's missing son. And when other victims vanish from the same upscale neighbourhood worry turns to terror.
