Mrs. Marrable (Geraldine Page) is a bereaved widow who takes to hiring housekeepers then kills them for their money in this shadowy macabre drama. When Miss Tinsley (Mildred Dunnick) disappears, her former employer Alice (Ruth Gordon) investigates. Posing as a maid, she gains employment with the murderous Mrs. Marrable. Her nephew Mike (Robert Fuller) helps Alice and manages to fall in love with the girl next door (Rosemary Forsythe). When Alice exposes the murderess, she risks her life, and her disappearance leads to the title of the film. Look for Second City alumnus Peter Bonerz in a minor role.
