Damaged nurse Meredith Stone (Patricia Pearcy) took a live-in caregiver's job with wealthy invalid Ivar Langrock (Joseph Cotten). While the employment became uncomfortable when the boss' aggressive young grandson (John Dukakis) moved into the estate, it became horrific when the other household retainers started getting brutally slain one by one. Who's responsible? Overlooked little chiller also stars David Hayward, Alice Dunn. 82 min. Widescreen; Soundtrack: English; Subtitles: English (SDH); audio commentary; featurettes.
