1x14 - Kolchak: The Night Stalker

A fashion industry spy is thrown to his death from a room filled with nothing but mannequins as Carl looks on from the street below. This is but the first in a series of strange murders that point to a supernatural origin: apparently Madame Trevi, a leading designer in the fashion industry, is using witchcraft to stop those who oppose her. With the aid of a witches' coven, Carl is pointed to the source of Trevi's power and destroys it, only to find who the witch truly is. Armed with a mojo bag, Carl must confront the witch and publicly accuse her to strip her of her powers.
