NOVA explores the different means by which hearing-impaired people have learned to penetrate the world of the hearing by visiting with Kitty O'Neil—a woman record-holding speed car racer; Frances Parsons, an advocate of hearing-impaired persons' rights; and workers at Silent Industries—a factory in Los Angeles founded by a deaf man.
