Rich American Margaret Landi (Crawford) is visiting her Irish homeland when she meets Esther (Sears), a young girl rendered deaf, mute, and blind by a childhood trauma. The childless Margaret is persuaded to take Esther in as a surrogate daughter and the waif gradually begins to respond to her care, sparking a media frenzy over the inspirational saga. This brings Carlo (Brazzi), Margaret's estranged and money-grubbing husband, out of the woodwork, with some get-rich-quick schemes. Well-done melodrama adapted from the book by Nicholas Monsarrat.
