This is a taut noir-horror-thriller hybrid about a serial killer who targets women with disabilities, and a mute woman’s efforts to avoid becoming the next victim. It’s very well shot, and has an ever-escalating feeling of claustrophobia and tension. I’m not a fan of Dorothy McGuire, but she’s quite good in a role that limits her to non-verbal communication.
