Kazuo Komizu, again using the pseudonym "Gaira," followed up his graphic 1986 film Bijo No Harawata with this even more lurid amalgam of graphic sex and stomach-churning violence. Three male photographers and their three female models drive down a lonely fog-blanketed road late at night and have to seek shelter in an isolated house, not knowing that a slimy zombie has risen from a nearby swamp and wants to kill them. The six engage in kinky sex games before being murdered in various gory ways. Eyes are popped from skulls, heads are lopped off, a man is hung from a metal hook, and so on. These events drive one of the models so crazy that she begins pleasuring herself with her dead boyfriend's severed arm before she is raped and disemboweled by the enormously endowed swamp monster. Quite a popular item in certain circles, the film's preoccupation with rape and violence toward women, while admittedly beyond the pale by American standards, is common in Japanese exploitation films.
