 Turn-of-the-century occultist Alfred Fischer acquires a mystical medallion and conjures up a trio of ravishing, ravenous demons from the depths of hell. Taking the form of beautiful women, the succubus beasts demand a steady diet of fresh human prey that only a mortal human servant can provide. Almost a century after Fischer meets his mysterious demise, a crack team of six parapsychologists investigate the manor and former brothel only to face an obstacle course of the seductive, sexy beasts, the madman owner with a satanic secret, and a horde of zombies making up of past victims bent on a rampage of carnal slaughter!
