The U.S. government, eager to protect the nation's avocado supplies, recruits feminist professor Margo Hunt to make contact with the Piranha Women, an all-female tribe who believe men are only good as a source of food. Accompanying Dr. Hunt on her trip are Jim, a guide of questionable competence, and Bunny, a student of unquestionable incompetence.

Mondo-style shockumentary about various aspects of the occult and paranormal. An investigation into the fringes of psychic spirituality with so-called experts, it includes demonic possession, exorcism, seances, Voodoo ceremonies, hypnotism, ESP, psychic surgery, and more. A warning bell alerts squeamish viewers to avert their eyes from the more graphic scenes.
