Miss Hepburn is perhaps too simple and trusting, and Alan Arkin (as a sadistic killer) is not particularly convincing in an exaggerated performance. But there are some nice, juicy passages of terror, and after a slow start the plot does seduce you.

Once this build-up is accomplished—once the sinister plot is launched and the young woman suddenly realizes that she has been duped and is in grave peril—the shock and suspense of the situation hit the audience with almost the same force, I'd imagine, as they evidently hit her. And from here on, the tension is terrific and the melodramatic action is wild as the blind woman uses all her courage and ingenuity to foil her assailants and save her life.
