On Sundays, Steve Belmont (Eli Rich) works at his local church as a teacher for the Department of Christian Education; the rest of the week he earns a meagre crust as a security guard, and spends his spare time picking up and killing women (mostly hookers), disposing of their bodies in the Mojave Desert.
Murderlust is a low budget mid-'80s serial killer flick that isn't grimy, gory or sleazy enough to get under the skin in the way that a classic like Henry: Portrait of a Serial Killer does. Eli Rich is fairly effective as the killer, effortlessly switching from concerned, upstanding citizen to worthless scumbag, and his relationship with unsuspecting blonde Cheryl (Rochelle Taylor) is nicely developed, but the pace severely drags in places, with the frequent appearance of his nosy cousin Neil (Dennis Gannon) being particularly dull.
The most exploitative scene comes when Steve forces one of his young victims, a rather plain looking schoolgirl, to fellate him at gunpoint; the act is suggested rather than shown, but it still proves to be the film's most memorable moment for at least attempting to push the envelope.
