(There are Spoilers) Better then expected made for TV movie about a serial killer on the loose who's being tracked by a cop who's trying to regain his memory that, among things, has the identity of just who the killer is. The movie "Shadow of Evil" is shot in an eerie green tint that makes it more creepy that it already is. The fact that the person in charge of the murder investigation Det. Jack Brenner, Treat Williams,is working with half his brain blacked out, due to amnesia, gives the unseen killer the edge that he needs to continue his murder spree.
After hitting his head on a rail chasing a suspect Brenner wakes up with his memory for the last six months wiped away. It's in those six months that Brenner identified who the serial killer, who's case he was in charge of, is. Not taking any notes because Brenner felt that the killer is a cop who he works with, and could get his hands on them at the police station, all the vital information to the killer's identity was lost together with Brenner's memory.
The police department gets neurologist Doctor Molly Nostrand, Margaret Coiln, to treat Brenner and get him to regain his lost memory. When it slowly starts to come back Brenner slowly starts to get paranoid with what he finds out about the killer.
Like a Three Card Monte game the movie keeps shifting the suspect, or actual killer, around with evidence that implicates almost everyone involved in the case including Det Brenner himself. There's the police pathologist Dr. Frank Teague, William H. Macy, who seems to always be away from his job or home when the serial murders are committed. Teague is also morbidly fascinated with the dead bodies that he operates on at the local morgue. There's also Brenners fellow cop Det. Keller, Timothy Busfield, who's dislike and attitude towards Brenner seem a bit more then jealousy. Is Keller afraid of what Brenner is about to find out to who the killer is? There's also Brenner's boss Let. Royce, Joe Morton, who's a bit too eager to get him off the case and looks for every excuse to do so. with Det. Keller doing everything possible to make it happen, is Royce hiding something?
There was an incident that involved a homeless man Noel Briggs, Tom Proctor,at the very start of the movie that was quickly forgotten that's the key to who the serial killer really is. It's not until much later that the person, Briggs, who Brenner chased on the railroad tracks reveals what he knows about the killings and that breaks the case, and Brenner's memory, wide open! But not the way you, and everyone in the cast including the killer himself, would have expected.
