In the title role, Stephanie Zimbalist is the sweet young thing who manipulates her way into the lives of Patty Duke Astin and William Shatner as their housekeeper and their daughter's sitter, and soon fills the family with horror and hate.  This psychological thriller reunited Zimbalist with her former teacher and drama department head at Juilliard, John Houseman, playing the doddering old doctor "from next door," in a "special guest appearance" (as TV credits like to read).
