The Mansfields are a family of four that live in Austin, TX who exclusively use the vibrant American Sign Language (ASL) as their home language as well as primarily out of the home. Manny, Sheena, and their oldest daughter Shaylee are deaf while their youngest daughter Ivy is hearing. They face scrutiny from their own families and the world for not incorporating speech at home for their hearing daughter Ivy. The Mansfields worry about the subtractive bilingualism that Ivy will face in the English dominated school system.
