The film plunges into the nightmarish experiences of a depressed psychic named Alley Oates (Deborah Rose), whose involvement in a grisly child-murder case leads her and her detective partner, Jersey Callum (Ed Nelson), to an imposing, fortress-like mortuary.

Chen (Robert Yun Ju Ahn), the owner of the funeral home and prime suspect in the case, claims the three mummified corpses in question are not children but ancient demons known as "kyoshi".

When Chen is jailed on murder charges, the under-fed ghouls awaken in search of dinner, trapping the staff inside the mortuary walls and devouring them.

The survivors, including Oates and Callum, use every means at their disposal to combat the demons, which have possessed the bodies of morgue attendant Mrs. Poopinplatz (Phyllis Diller) and her poodle, mutating them into hideous monsters.

[5] Adam Tyner of DVD Talk rated it 2.5/5 stars and said that the film wastes too much time on setup rather than the campy monsters that have brought it a cult following.
