It's zombies Vs. cannibals in a mediocre genre mash-up from the producer of ZOMBI II. This was actually released at some point as ZOMBI III, and it easily could have been a sequel. While it has some creative kills and cool moments, it just doesn't have the consistent "what the fuck?" that ZOMBI II has.
He's a depraved, homicidal killer...and he makes house calls!
