A serial killer, Patrick Channing (the great Jeff Kober) is stalking LA with ritualistic murders involving occultism and devil worshipping. Lou is the twelve year old super-cop Russell Logan who finally catches him and watches him die in the electric chair. But some time after the killings starts all over again and Russell sees and hears visions of Patrick. A psychic, Tess Seaton (Tracy Griffith) helps him, because no one else believes in Russell's visions. Yes, Patrick is back from the dead and he's using the bodies of drug addicts to continue his killing spree!
One of the best scenes - and the only one I remember from when I first saw it - is when the killer is taking control over a ceiling fan and chases our heroes out from an old building, climaxing in a nice stuntman-hanging-on-to-a-car-stunt that looks very dangerous.
