Kazuo Komizu's gory thriller dares to explore the myth of otherworldly creatures that go "bump" in the night. In this case, the creature's not only an eerie specter, it's a murderous one, too. Its victims of choice? Three alluring models (Naomi Hagio, Megumi Kawashima and Saeko Kizuki) who are stranded in the woods and hole up in a dilapidated cabin during a dense fog. A killer swamp monster soon tracks them down and forces them to be sex slaves.
