Based on the history of Nicaraguan Sign Language.

Nicaragua in the 1970s had no official form of sign language. In 1977 fifty deaf children from across the country were brought together to a school in Managua. Without a shared language to express themselves, the children did something remarkable—they created one. In Sign, we follow a story inspired by that journey. Played completely in silence. One person is the teacher and all other players are students. The game is split between recess and classroom sessions and players create their own language through play.
