After a nasty confrontation with business rival Joyce Chapman (Linda Lawson), career woman Karen Wadsworth (Joanne Linville) expresses the wish that Joyce were dead--and before long, the wish comes true. Coincidence? Karen doesn't think so, especially after it appears that she has "willed" the deaths of a few other people. Consulting a psychiatriast (John Kellogg), Karen is assured that she is only imagining things. It's a persuasive argument, at least until Karen makes just one more casual comment...or should we say, just one "famous last word"?
