Mockingbird Don't Sing is a 2001 drama, based on true events, directed by Harry Bromley Davenport. In the film, Katie (Terra Steele) has been rescued by authorities after suffering years of physical and emotional abuse by her psychotic parents. The 13-year-old teenager has been kept in isolation for almost ten years. When she was finally rescued, she was barely able to walk, not toilet-trained and doctors discovered she had never learned to speak and could not understand any type of language. Instead, Katie communicated by spitting, sniffing and clawing at the people who were trying to treat her. Medical and psychological doctors were fascinated with her case. She was an actual feral child and many of them only wanted to help her in hopes of becoming famous for their work. Unfortunately, the doctors constant testing deepened the emotional wounds Katie had already endured. The film portrays her difficult journey from her imprisonment by her parents to her discovery of herself.
