Andre and Leslie are a deaf couple who have decided to have a child, and they’re considering using a process to ensure deafness in their child. As deaf parents, they feel they could provide better guidance to a child that would share their lived experience and grow up immersed in deaf culture. But is this genetic intervention ethical? Michael Vazquez and Raye Ploeger explore this classic dilemma. [Directed by Luisa Holanda, narrated by Bethany Cutmore-Scott, music by Gabriel Maia].
