Some 8 months after the events of Part 1, and it seems not only did Dr Herbert West (Jeffrey Combs) survive the ordeal at the Miskatonic hospital morgue but has been spending the elapsed time with his partner, Dr Dan Cain (Bruce Abbott) working as medical missionaries in Peru, where a vicious civil war has erupted (cue lots of bloody surgery scene's and Dr West taking on the whole invading army with his pistol, when the camp is overrun).
The war has been providing Dr's West and Cain with plenty of specimens to experiment with, thus allowing them to improve and refine the re-animation agent. Believing they can create life by stitching togethor various body parts, they return home, taking up positions at the Miskatonic University Hospital, where Dr West proceeds to plunder the morgue, for spare body parts in order to build the perfect woman.
Unfortunately, things start to go wrong when a bungling detective startsinvestigating his antics and finds out what he's been up to, and subsequently ends up going the same way as the late Dr Hill. To make matters worse Dr Hill's head (David Gale again) is re-activated by an investigating doctor, who's been experimenting with some of West's Re-Animation agent in the police evidence room, who subsequently enlists the help of the re-animated police officer and the zombies left over from the last film, which currently reside in the hospitals loony bin, to gop after him.
More darkly humoured antics follow, as Dr West goes around building bizarre creations out of spare body parts, Dr Hill has a pair of bat wings attached to his severed head and goes flying round Herbert's house, and finally Dr West's creation "Gloria" comes to life, only to reject his advances and get the hots for Dr Cain instead.
As you can gather, this is basically a rather cheeky reworking of "The Bride of Frankenstein". The gore in this movie is still quite phenomenal, although not quite as much as Part 1, but its a highly enjoyable sequel, virtually as good as the first.
