This video is about how learning sign language changes the world for deaf people.

Patrick Otema, 15 was born profoundly deaf. In the remote area of Uganda where he lives there are no schools for deaf children, and he has never had a conversation. Raymond Okkelo, a sign language teacher, hopes to change all this and offer Patrick a way out of the fearful silence he has known his whole life.
