Wait Until Dark is an innovative, highly entertaining and suspenseful thriller about a blind housewife, Susy Hendrix (Audrey Hepburn). Independent and resourceful, Susy is learning to cope with her blindness, which resulted from a recent accident. She is aided by her difficult, slightly unreliable young neighbor Gloria (Julie Herrod) with whom she has an exasperated but lovingly maternal relationship. Susy's life is changed as she is terrorized by a group of criminals who believe she has hidden a baby doll used by them to smuggle heroin into the country. Unknown to Susy, her photographer husband Sam (Efrem Zimbalist Jr.) took the doll as a favor for a woman he met on an international plane flight and unwittingly brought the doll to the couple's New York apartment when the woman became afraid of the customs officials. Alone in her apartment and cut-off from the outside world, Susy must fight for her life against a gang of ruthless criminals, led by the violent, psychotic Roat (Alan Arkin).
