Dr. Warren Chapin has made a surprising discovery -- the spine-chilling sensation that people get when scared is due to a parasite that he dubs the ''tingler.'' Chapin concludes that in extreme circumstances, prolonged fear can cause the creature to damage a person's spine and even cause death if the victim can't scream, a theory that Oliver Higgins uses to deadly effect on his wife . Soon the tingler that killed the woman is on the loose.
